MyFaces 1.1.1 has duplicate ID problems. Upgrade
to 1.1.2 or higher.

I had been getting a duplicate id error in my JSF app

As you
can see from the stack trace, I am using MyFaces (v. 1.1.1),
Facelets
(1.10). I kept eliminating code from the offending XHTML
and
narrowed the problem down to the header facet inside a
datatable:
<h:commandLink action="" >Post back to this
page</h:commandLink>
<t:datatable
...>
<t:column>
<h:facet
name="header">
<h:panelGroup>A
Header</h:panelGroup>
</h:facet>
Column
Contents
</t:column>
</t:datatable>
Basically,
if I changed:
<h:panelGroup>A Header</h:panelGroup> to
<h:panelGroup id="someId">A
Header</h:panelGroup>
I no
longer had the problem. Has anyone else experienced this
problem?
I found a couple of JIRA issues that sounded similar to this
problem,
but nothing concrete. Is this fixed in the latest
release?
