Re: [tobago] and facelets: using composition

Sun, 26 Oct 2008 13:30:35 -0700 

Hi,
when I change the getConstraints mehtod to create a constraints instance (like in UIInputBase) the next NullPointerException arises when accessing width and height - thought there is an (this$0) instance which contains the information (as strings). 


I'll take a look at this when I have some more time - if you have any 
hint how to proceed I'd be happy!


Regards,

Stefan.

Hi,


I've updated to revision 708014. Before the warnings about the 
unbalanced layout appear in the logs now a NullPointerException is 
printed in LayoutContext line 49. The field container returns null for 
container.getConstraints().



Maybe I have to add some configuration so the new LayoutContext will 
work with the container?


Regards,

Stefan.

Hello Stefan,

the 1.1.x trunk is a little bit buggy now. We try to refactor the
layouting and many other parts of Tobago. I can look at your issue at
the weekend.

Hi,

I'm switching from using jsp to faclets and am currently working on a

prototype using tobago-1.1.0-SNAPSHOT and sun RI 1.2 on JBoss. I 
started

with a layout which worked for jsps, and began to migrate it to

facelets. As this didn't work as expected I tried to simplify the 
layout

and finally came to a point where I only have three parts in my layout:
a header, the body (content) and a footer. But I still get weird rows
with 0px height and columns with 0px width in the resulting html.

Here is some code:

app/home.xhtml:

 <ui:composition template="/templates/master.xhtml">
   <tc:loadBundle basename="bundle" var="mainBundle" />
   <ui:define name="title">#{mainBundle.pageTitle}</ui:define>
   <ui:define name="body">
     <tx:date id="test" label="Label"/>
   </ui:define>
 </ui:composition>

templates/master.xhtml:

 <f:view locale="#{clientConfiguration.locale}">
   <tc:loadBundle basename="bundle" var="mainBundle" />
   <tc:page label="#{mainBundle.pageTitle}" id="masterpage" width="800"
height="600">

     <f:facet name="layout">
       <tc:gridLayout border="1" margin="1px" columns="*"
rows="fixed;fixed;*;fixed"  />
     </f:facet>

     <!-- row 0 -->
     <tc:link action="app/home" immediate="true"
         image="image/logo_tiny.gif" />

     <!-- row 1 -->
     <ui:insert name="body">
       <ui:include src="/templates/body.xhtml"/>
     </ui:insert>
     <!-- row 2 -->
     <tc:cell/>

     <!-- row 3 -->
     <tc:out value="#{mainBundle.copyrightNote}"/>

   </tc:page>
 </f:view>

templates/header.xhtml

 <f:subview id="header">
   <tc:loadBundle basename="bundle" var="mainBundle" />
   <tc:link action="app/home" immediate="true"
       image="image/logo_tiny.gif" />
 </f:subview>

(footer is similar to header so I skip this one).

The result is (excerpt only :))


<table border="1" class="tobago-gridLayout-default" 
style="height:600px;

width:800px; " cellspacing="0" cellpadding="0" summary=""

   

<colgroup
<col width="796"
</colgroup><tr

<td class="tobago-gridLayout-cell-td" style="width: 796px; height: 
0px;"

<div class="tobago-gridLayout-default tobago-gridLayout-first-row
tobago-gridLayout-first-column" style="width: 796px; height: 0px;"


      

     <!-- row 0 --></div></td></tr><tr

   

<td class="tobago-gridLayout-cell-td" style="width: 796px; height: 
25px;"

<div class="tobago-gridLayout-default tobago-gridLayout-first-column"
style="width: 796px; height: 25px;"
<a href="javascript:;" onclick="Tobago.submitAction(this,
'masterpage:j_id4', true);" class="tobago-link-default"
id="masterpage:j_id4" name="masterpage:j_id4"
<img

src="/seam-template/tobago-resource/html/standard/standard/image/logo_tiny.gif" 


border="0" alt=""
</a></div></td></tr><tr
<td class="tobago-gridLayout-cell-td" style="width: 796px; height:
108px;"
<div class="tobago-gridLayout-default tobago-gridLayout-first-column"
style="width: 796px; height: 108px;"


      

I get the following warnings in the log (as far as I know row is used
for both row and column in the output):


22:21:06,164 WARN  [GridLayoutRenderer] Unbalanced layout: 
rows.size()=8

!=layoutTokens.length=4 rowLayout='fixed;fixed;1*;fixed;'
(clientId='masterpage:j_id2')
22:21:06,213 WARN  [GridLayoutRenderer] Unable to calculate Height for
token '1*'! using 'fixed' , component:masterpage:j_id6 is Panel
22:21:06,308 WARN  [GridLayoutRenderer] Unable to calculate Height for
token '1*'! using 'fixed' , component:masterpage:j_id6 is Panel
2

Has anyone used tobago and facelets for this kind of composite layout?
How do I avoid these 0px wide columns / high rows? (You can imagine the
more complex the layout the more weird the result ...)

Any hints welcome!

Best regards,

Stefan.
