a4j:support + a4j:outputPanel problem

[sambolino]

hello

could someone explain please why one of these works and the other doesn't, and if it is expected behavior (although i don't see a reason why it should be):

<h:selectOneMenu ... >
...
<a4j:support event="onchange" reRender="abc" bypassUpdates="false" />
</a4j:support>
</h:selectOneMenu>

this works:
<s:decorate id="abc" ... >
...
<h:inputText rendered="#{expr1}" />
</s:decorate>

but this doesn't:
<a4j:outputPanel id="abc" rendered="#{expr1}"
<s:decorate ... >
...
<h:inputText />
</s:decorate>
</a4j:outputPanel>

conditionaly rendered element should not be reREndered directly. There are clear limitation in dev guide.

use reRendering of the parent itself.

thanks thats pretty straight and useful. i'll post this trivial solution to my case

so this works:

<a4j:outputPanel id="abc" >
<a4j:outputPanel rendered="#{expr1}" >
<s:decorate ... >
...
<h:inputText />
</s:decorate>
</a4j:outputPanel>
</a4j:outputPanel>
