Tapestry component id (<code>t:id</code>).</p><p>However, there are any number
of exceptions to this rule. The Zone may be rendering inside a Loop (in which
case, each rendering will have a unique client side id). The Zone may be
rendering as part of a partial page render, in which case, a random unique id
is inserted into the id. There are other examples where Tapestry component ids
in nested components may also clash.</p><p>The point is, to be sure, specify

do I get exceptions about instantiating a bean when using
BeanEditForm?</h2><p>When you render a BeanEditForm, or when the rendered form
is submitted, Tapestry must instantiate an instance of the object to be edited.
This occurs when the BeanEditForm's <code>object</code> parameter is bound to
null: Tapestry instantiates an instance of the property type so that the
BeanEditForm has an object to read default values from, or to push submitted
values into.</p><p>By default, this uses the standard <a
href="injection-in-detail.html">injection mechanism</a>, which means that
Tapestry will identify the public constructor with the most parameters, and
attempt to find objects and other objects for each constructor
parameter.</p><p>There's two ways to fine tune this so you don't get
errors:</p><ul><li>Place an @<a class="external-link"

<p>One of the best features of Tapestry is automatic reloading of changed
classes and templates. <em>Page and component</em> classes will automatically
reload when changed. Likewise, changes to component templates and other related
resources will also be picked up immediately. In addition, starting in version
5.2, your service classes will also be reloaded automatically after changes (if
you're using <a href="ioc.html">Tapestry IoC</a>). Starting in version 5.8.3,
you enable multiple classloader mode, which allows smarter page class

extension of the <a class="external-link"

operation that updates server-side state, such as a form submission, if the
user resubmits the resulting page, the operation is <strong>not</strong>
performed a second time; instead just the results of the operation, reflecting
the changed server-side state, is re-rendered.</p><p>This has the unwanted
requirement that any data needed to render the response must persist between
the event request (the form submission) and the render request; this often
means that fields must be annotated with @<a class="external-link"

<code>t:formdata</code> hidden field for?</h2><p>In Tapestry, rendering a form
can be a complicated process; inside the body of the Form component are many of
field components: TextField, Select, TextArea, and so forth. Each of these must
pull data out of your data model and convert it to the string form used inside
the client web browser. In addition, JavaScript to support client-side
validation must be generated. This can be further complicated by the use of
Loop and If components, or made really complicated by the use of Block (to
render portions of other pages: this is what the BeanEditForm component
does).</p><p>Along the way, the Form is generating unique form control names
for each field component, as it renders.</p><p>When the client-side Form is
submitted, an event is triggered on the server-side Form component. It now
needs to locate each component, in turn, inform the component of its
control name, and allow the component to read the corresponding query
parameter. The component then converts the client-side string back into a
server-side value and performs validations before updating the data
model.</p><p>That's where <code>t:formdata</code> comes in. While components
are rendering, they are using the FormSupport environmental object to record
callbacks:</p><div class="code panel pdl" style="border-width: 1px;"><div

populating their fields, and validating user input. For simple cases, input
validation is declarative, meaning you simply tell Tapestry what validations to
apply to a given field, and it takes care of it on the server and (optionally)
on the client as well. In addition, you can provide event handler
methods in your page or component classes to handle more complex
validation scenarios.</p><p>Finally, Tapestry not only makes it easy to present

</div><h2 id="GeneralQuestions-HowdoIgetstartedwithTapestry?">How do I get
started with Tapestry?</h2><p class="confluence-link">The easiest way to get
started is to use <a class="external-link"
href="http://maven.apache.org";>Apache Maven</a> to create your initial project;
Maven can use an <em>archetype</em> (a kind of project template) to create a
bare-bones Tapestry application for you. See the <a
href="getting-started.html">Getting Started</a> page for more
details.</p><p>Even without Maven, Tapestry is quite easy to set up. You just
need to <a href="general-questions.html">download</a> the binaries and setup
your build to place them inside your WAR's WEB-INF/lib folder. The rest is just
some one-time <a href="configuration.html">configuration of the web.xml
deployment descriptor</a>.</p><h2
id="GeneralQuestions-WhydoesTapestryusePrototype(inversionsbefore5.4)?WhynotinsertfavoriteJavaScriptlibraryhere?">Why
does Tapestry use Prototype (in versions before 5.4)? Why not <em>i
nsert favorite JavaScript library here</em>?</h2><p>An important goal for
Tapestry is seamless DHTML and Ajax integration. To serve that goal, it was
important that the built in components be capable of Ajax operations, such as
dynamically re-rendering parts of the page. Because of that, it made sense to
bundle a well-known JavaScript library as part of Tapestry.</p><p>At the time
(this would be 2006-ish), Prototype and Scriptaculous were well known and well
documented, whereas jQuery was just getting started.</p><p>The intent has
always been to make this aspect of Tapestry pluggable. Tapestry 5.4 includes
the option of either Prototype or jQuery, and future versions of Tapestry will
likely remove Prototype as an option..</p><h2
id="GeneralQuestions-WhydoesTapestryhaveitsownInversionofControlContainer?WhynotSpringorGuice?">Why
does Tapestry have its own Inversion of Control Container? Why not Spring or
Guice?</h2><p>An Inversion of Control Container is <em>the</em> key piece of
Tape
stry's infrastructure. It is absolutely necessary to create software as
robust, performant and extensible as Tapestry.</p><p>Tapestry IoC includes a
number of features that distinguish itself from other
containers:</p><ul><li>Configured in code, not XML</li><li>Built-in extension
mechanism for services: configurations and contributions</li><li>Built-in
aspect oriented programming model (service decorations and advice)</li><li>Easy
modularization</li><li>Best-of-breed exception reporting</li></ul><p>Because
Tapestry is implemented on top of its IoC container, and because the container
makes it easy to extend or replace any service inside the container, it is
possible to make the small changes to Tapestry needed to customize it to any
project's needs.</p><p>In addition – and this is critical –
Tapestry allows 3rd party libraries to be built that fully participate in the
configurability of Tapestry itself. This means that such libraries can be
configured the same way T
apestry itself is configured, and such libraries can also configure Tapestry
itself. This <em>distributed configuration</em> requires an IOC container that
fully supports such configurability.</p><h2
id="GeneralQuestions-HowdoIupgradefromTapestry4toTapestry5?">How do I upgrade
from Tapestry 4 to Tapestry 5?</h2><p>There is no existing tool that supports
upgrading from Tapestry 4 to Tapestry 5; Tapestry 5 is a complete
rewrite.</p><p>Many of the basic concepts in Tapestry 4 are still present in
Tapestry 5, but refactored, improved, streamlined, and simplified. The basic
concept of pages, templates and components are largely the same. Other aspects,
such as server-side event handling, is markedly different.</p><p>Tapestry 5 is
designed so that it can live side-by-side in the same servlet as a Tapestry 4
app, without package namespace conflicts, sharing session data and common
resources such as images and CSS. This means that you can gradually migrate a
Tapestry 4 app to Tapestry 5 one
page (or one portion of the app) at a time.</p><h2
id="GeneralQuestions-HowdoIupgradefromoneversionofTapestry5toanother?">How do I
upgrade from one version of Tapestry 5 to another?</h2><p>Main Article: <a
href="how-to-upgrade.html">How to Upgrade</a>.</p><p>A lot of effort goes into
making an upgrade from one Tapestry 5 release to another go smoothly. In the
general case, it is just a matter of updating the version number in your Maven
<code>build.xml</code> or Gradle <code>build.gradle</code> file and executing
the appropriate commands (e.g., <code>gradle idea</code> or <code>mvn
eclipse:eclipse</code>) to bring your local workspace up to date with the
latest binaries.</p><p>After changing dependencies, you should always perform a
clean recompile of your application.</p><p>We make every effort to ensure
backwards-compatibility. Tapestry is mostly coded in terms of interfaces; those
interfaces are stable to a point: interfaces your code is expected to implement
are usually complet
ely frozen; interfaces your code is expected to invoke, such as the interfaces
to IoC services, are stable, but may have new methods added in a release;
existing methods are not changed.</p><p>In <em>rare</em> cases a choice is
necessary between fixing bugs (or adding essential functionality) and
maintaining complete backwards compatibility; in those cases, an incompatible
change may be introduced. These are always discussed in detail in the <a
href="release-notes.html">Release Notes</a> for the specific release. You
should always read the release notes before attempting an upgrade, and always
(really, <em>always</em>) be prepared to retest your application
afterwards.</p><p>Note that you should be careful any time you make use of
<strong>internal</strong> APIs (you can tell an API is internal by the package
name, <code>org.apache.tapestry5.internal). </code>Internal APIs may change
<em>at any time</em>; there's no guarantee of backwards compatibility. Please
always check on th
e documentation, or consult the user mailing list, to see if there's a stable,
public alternative. If you do make use of internal APIs, be sure to get a
discussion going so that your needs can be met in the future by a stable,
public API.</p><h2
id="GeneralQuestions-WhyaretherebothRequestandHttpServletRequest?"><span
style="color: rgb(83,145,38);">Why are there both Request and
HttpServletRequest?</span></h2><p>Tapestry's Request interface is <em>very</em>
close to the standard HttpServletRequest interface. It differs in a few ways,
omitting some unneeded methods, and adding a couple of new methods (such as
<code>isXHR()</code>), as well as changing how some existing methods operate.
For example, <code>getParameterNames()</code> returns a sorted List of Strings;
HttpServletRequest returns an Enumeration, which is a very dated
approach.</p><p>However, the stronger reason for Request (and the related
interfaces Response and Session) is to enable the support for Portlets at some
point
in the future. By writing code in terms of Tapestry's Request, and not
HttpServletRequest, you can be assured that the same code will operate in both
Servlet Tapestry and Portlet Tapestry.</p></div>

</div><p>You may have an existing JSP (or Struts, Spring MVC, etc.)
application that you want to migrate to Tapestry. It's quite common to do this
in stages, moving some functionality into Tapestry and leaving other parts,
initially, in the other system. <a href="request-processing-faq.html">You may
need to prevent Tapestry from handling certain requests</a>.</p><h2
id="Integrationwithexistingapplications-HowdoImakeaformonaJSPsubmitintoTapestry?">How
do I make a form on a JSP submit into Tapestry?</h2><p>Tapestry's Form
component does a lot of work while an HTML form is rendering to store all the
information needed to handle the form submission in a later request; this is
all very specific to Tapestry and the particular construction of your pages and
forms; it can't be reproduced from a JSP.</p><p>Fortunately, that isn't
necessary: you can have a standard HTML Form submit to a Tapestry page, you
just don't get to use all of Tapestry's built in conversion and validation
logic.</p><p>
All you need to know is how Tapestry converts page class names to page names
(that appear in the URL). It's basically a matter of stripping off the
<em>root-package</em>.<code>pages</code> prefix from the fully qualified class
name. So, for example, if you are building a login screen as a JSP, you might
want to have a Tapestry page to receive the user name and password. Let's
assume the Tapestry page class is
<code>com.example.myapp.pages.LoginForm</code>; the page name will be
<code>loginform (although, since </code><span>Tapestry is case
insensitive, LoginForm would work just as well)</span><span>, and the URL will
be </span><code>/loginform</code><span>.</span></p><div class="code panel pdl"

means your browser has not been able to load the tapestry.js file properly. The
question is, why? It can be due to multiple reasons, some of them
below:</p><ul><li>First, check if 'tapestry.js' is present in the head part of
your resulting HTML page.</li><li><p>If you have set the <a
href="configuration.html">tapestry.combine-scripts</a> configuration symbol to
true, Tapestry generates one single URL to retrieve all the JS files.
Sometimes, this can produce long URLs that browsers are unable to retrieve. Try
setting the symbol to false.</p><div class="confluence-information-macro

class="confluenc

5.1.</p></div></div></li><li>If you have included jQuery in conjunction with
Tapestry's prototype, that will cause a conflict with the '$' selector used by
both. In this case, you should put jQuery on top of the stack and turn on the
<a class="external-link" href="http://api.jquery.com/jQuery.noConflict/";
rel="nofollow">jQuery.noConflict</a> mode.</li><li>Also, if you have included a
custom or third-party JS library on top of the stack that causes the JavaScript
parsing to fail, then check the JavaScript syntax in that library.</li><li>If
you have used a tool to minimize your JavaScript libraries, this can lead to
JavaScript syntax errors, so check if it works with all the JavaScript files
unpacked.</li></ul><h2
id="JavaScriptFAQ-What'sthedifferencebetweentheT5objectandtheTapestryobjectinthebrowser?(5.3andearlier)">What's
the difference between the <code>T5</code> object and the
<code>Tapestry</code> object in the browser? (
5.3 and earlier)</h2><p>Both of these objects are <em>namespaces</em>:
containers of functions, constants, and nested namespaces.</p><p>The
<code>T5</code> object is a replacement for the <code>Tapestry</code> object,
starting in release 5.3. Increasingly, functions defined by the
<code>Tapestry</code> object are being replaced with similar or equivalent
functions in the <code>T5</code> object.</p><p>This is part of an overall goal,
spanning at least two releases of Tapestry, to make Tapestry JavaScript
framework agnostic; which is to say, not depend specifically on Prototype or
jQuery. Much of the code in the <code>Tapestry</code> object is specifically
linked to Prototype and Scriptaculous.</p><p>The <code>T5</code> object
represents a stable, documented, set of APIs that are preferred when building
components for maximum portability between underlying JavaScript frameworks. In
other words, when building component libraries, coding to the <code>T5</code>
object ensures that your c
omponent will be useful regardless of whether the final application is built
using Prototype, jQuery or something else.</p></div>

id="Limitations-HowdoIaddnewcomponentstoanexistingpagedynamically?">How do I
add new components to an existing page dynamically?</h2><p>The short answer
here is: <strong>you don't</strong>. The long answer here is <strong>you don't
have to, to get the behavior you desire</strong>.</p><p>One of Tapestry basic
values is high scalability: this is expressed in a number of ways, reflecting
scalability concerns within a single server, and within a cluster of
servers.</p><p>Although you code Tapestry pages and components as if they were
ordinary POJOs (<span>Plain Old Java Objects -- Tapestry does not require you
to extend any base classes or implement any special interfaces)</span><span>,
as deployed by Tapestry they are closer to a traditional servlet: a single
instance of each page services requests from multiple threads. Behind the
scenes, Tapestry transforms you code, rewriting it on the
fly.</span></p><p>What this means is that <em>any</em> incoming request must be
handled
by a <em>single page instance</em>. Therefore, Tapestry enforces the concept
of <strong>static structure, dynamic behavior</strong>.</p><p>Tapestry provides
quite a number of ways to vary what content is rendered, well beyond simple
conditionals and loops. It is possible to "drag in" components from other pages
when rendering a page (other FAQs will expand on this concept). The point is,
that although a Tapestry page's structure is very rigid, the order in which the
components of the page render does not have to be top to bottom.</p><h2

service must define a service interface.</li><li>The service implementation

id="PageAndComponentClassesFAQ-What'sthedifferencebetweenapageandacomponent?">What's
the difference between a page and a component?</h2><p>There's very little
difference between the two. Pages classes must be in the
<em>root-package</em>.<code>pages</code> package; components must be in the
<em>root-package</em>.<code>components</code>. Pages may provide event handlers
for certain page-specific events (such as activate and passivate). Components
may have parameters.</p><p>Other than that, they are more equal than they are
different. They may have templates or may render themselves in code (pages
usually have a template, components are more likely to render only in
code).</p><p>The major difference is that Tapestry page templates may be stored
in the web context directory, as if they were static files (they can't be
accessed from the client however; a specific rule prevents access to files with
the <code>.tml</code> extension).</p><div class="confluence-information-macro co

class="confluence-information-macro-body"><p>It is possible that this feature
may be removed in a later release. It is preferred that page templates be
stored on the classpath, like component templates.</p></div></div><h2
id="PageAndComponentClassesFAQ-HowdoIstoremypageclassesinadifferentpackage?">How
do I store my page classes in a different package?</h2><p>Tapestry is very
rigid here; you can't. Page classes must go in
<em>root-package</em>.<code>pages</code>, component classes in
<em>root-package</em>.<code>components</code>, etc.</p><p>You are allowed to
create sub-packages, to help organize your code better and more logically. For
example, you might have
<em>root-package</em>.<code>pages.account.ViewAccount</code>, which would have
the page name "account/viewaccount". (<span>Tapestry would also create an alias
"account/view", by stripping of
f the redundant "account" suffix. Either name is equally valid in your code,
and Tapestry will use the shorter name, "account/view" in
URLs.)</span></p><p>In addition, it is possible to define additional root
packages for the application:</p><div class="code panel pdl"

</p><p>In a Tapestry application, most application classes are loaded from the
middle class loader. Additional class loaders are used to support live service
reloading, and live component reloading (along with component class
transformation).</p><p>When a page or component is passed as a parameter to a
service, a failure occurs (how it is reported varies in different JDK releases)
because of the class mismatch.</p><p>The solution is to define an interface
with the methods that the service will invoke on the page or component
instance. The service will expect an object implementing the interface (and
doesn't care what class loader loaded the implementing class).</p><p>Just be
sure to put the interface class in a non-controlled package, such as your
application's <em>root-package</em> (and <strong>not</strong>
<em>root-package</em>.<code>pages</code>).</p><h2
id="PageAndComponentClassesFAQ-Whichisbetter,usingmagicmethodnames(i.e.,beginRender())orannotations(i.e.BeginRender)?">Which
is
better, using magic method names (i.e., <code>beginRender()</code>) or
annotations (i.e. <code>BeginRender</code>)?</h2><p>There is no single best
way; this is where your taste may vary. Historically, the annotations came
first, and the method naming conventions came later.</p><p>The advantage of
using the method naming conventions is that the method names are more concise,
which fewer characters to type, and fewer classes to import.</p><p>The main
disadvantage of the method naming conventions is that the method names are not
meaningful. <code>onSuccessFromLoginForm()</code> is a less meaningful name
than <code>storeUserCredentialsAndReturnToProductsPage()</code>, for
example.</p><p>The second disadvantage is you are more susceptible to
off-by-a-character errors. For example, <code>onSucessFromLoginForm()</code>
will <em>never</em> be called because the event name is misspelled; this would
not happen using the annotation approach:</p><div class="code panel pdl"

<p>In essence, a Tapestry application is a number of related pages, working
together. To some degree, each page is like an application unto
itself.</p><p>Any individual request will be targeted at a single page.
Requests come in two forms: </p><ul><li><em>component event</em> requests
target a specific component on a specific page, triggering an event within that
component</li><li><em>render</em> requests target a specific page, and stream
the HTML markup for that page back to the client</li></ul><p>This dichotomy
between component event requests and render requests alleviates a number of
problems in traditional web applications related to the browser back button, or
to the user hitting the refresh button in their browser.</p><h3
