Hi Leonardo,
I am using the latest trunk snapshot updated today. I'm aware of MYFACES-3853
(I reported it) and the issue reported there is indeed resolved, but this
problem is different. It seems that component state is being written to
incorrect components. In this case it seems that a ForEach tag state was
written to a If tag state resulting in the stack trace you see above.
Strangely enough, removing simple div tags seems to remove this error in a
number of situations:
This produces the error (this is just a fragment of the view):
<div>
<div>
<h5 id="randomId">
<c:if test="#{customComponent.condition1}">
<p>Test1</p>
</c:if>
<c:if test="#{customComponent.condition2}">
<p>Test2</p>
</c:if>
<c:if test="#{customComponent.condition3}" >
<p>Test3</p>
</c:if>
<c:if test="#{customComponent.condition4}" >
<p>Test4</p>
</c:if>
</h5>
</div>
</div>
However, removing the <div> tags makes the page render without errors.
<h5 id="randomId">
<c:if test="#{customComponent.condition1}">
<p>Test1</p>
</c:if>
<c:if test="#{customComponent.condition2}">
<p>Test2</p>
</c:if>
<c:if test="#{customComponent.condition3}" >
<p>Test3</p>
</c:if>
<c:if test="#{customComponent.condition4}" >
<p>Test4</p>
</c:if>
</h5>
Additionally, if we remove all of the if tags instead, this makes the page
render without errors.
<div>
<div>
<h5 id="randomId">
<p>Test1</p>
<p>Test2</p>
<p>Test3</p>
<p>Test4</p>
</h5>
</div>

> Error during Restore Phase when using ajax and partial view re-rendering
