--------------------------------------------
Summary: Ajax's render doesn't support nested elements
Key: MYFACES-4695
URL: https://issues.apache.org/jira/browse/MYFACES-4695
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 4.1.0-RC3, 4.0.2, 2.3-next-M8, 3.0.2, 2.3.10
Reporter: Volodymyr Siedlecki
The code below doesn't work as expected. The element with id "one" should be
updated. Instead, the submit is rendered when pressed.
{code:java}
<h:body>
TEMPLATE
<h:form id="cartForm">
CART IS HERE!
<h:outputText id="one" value="1" />
<h:outputText id="two" value="2" />
</h:form>
<h:form id="shoppingCartForm" name="shoppingCartForm">
<h:commandButton type="submit" value="Update"
styleClass="commandExButton" id="updateButton">
<f:ajax execute="@form" render="cartForm:one" />
</h:commandButton>
</h:form>
</h:body>
</f:view>
{code}
The generated code looks like:
{code:java}
<input id="shoppingCartForm:updateButton" name="shoppingCartForm:updateButton"
type="submit" value="Update" onclick="faces.util.chain(this,
event,function(event){myfaces.ab(this,event,'action','@form','shoppingCartForm:updateButton')});
return false;" class="commandExButton"> {code}
The ids for the render are the submit button itself:
*shoppingCartForm:updateButton*
Note: Mojarra works as expected (element one is updated) when I tested the
same facelet.
Note: 4.1.0-RC3 fails with the following exception (due to
[MYFACES-4624|https://github.com/apache/myfaces/commit/304099d4588383424df9105d5a751911c1c5301a]):

The solution in my opinion is the let the search in the invokeOnComponent
method call continue without regard of the separator character. The parent
naming contains would be searched until the id is found (or not).
In other words, remove this line:
