rich:simpleTogglePanel -- cannot set default to "closed"!

[acgrama]

Hi all,

I have trouble setting the default state for rich:simpleTogglePanel as closed. Below, some relevant snippets from my xhtml, showing what I'm doing. Basically, I collect some input data, and when the Search Similar Problems button is pressed, I do some computation and show results in a table with one column and a rich:simpleTogglePanel in every row.

<h:form>
...collect some data...
<h:commandButton id="searchSimilarProblems" value="Search Similar Problems"
     action="#{searchSimilarProblems.searchSimilarProblems}" reRender="similarProblemsResult_id"/>
     
<a4j:outputPanel id="similarProblemsResult_id">
    <rich:dataTable value="#{similarProblems}" var="similarProblem" columnsWidth="0*" width="700">
     <rich:column>
         <f:facet id="ProblemAreaFacet" name="header">Similar Problems Found</f:facet>                         
         <rich:simpleTogglePanel switchType="ajax" label="#{similarProblem.caseId}" opened="false">
             ...
         </rich:simpleTogglePanel>   
     </rich:column>
    </rich:dataTable>
</a4j:outputPanel>     
     
</h:form>

I have tested a rich:simpleTogglePanel outside the table, and, for that case, setting opened to false worked. Any ideas or suggestions regarding why this is not working in the table?
Thanks in advance!

Try setting an id for each of the simple toggle panels. I've found that to help with nested rich components.

Thank you for the fast reply! I tried to use ids for the various components and added them to the reRender list of the command button, but had no luck.

(I suspect the embedding of the toggle panel in the table makes it invisible somehow for setting its open/close state. I tried a small experiment and added rendered with value false as attribute to the toggle panel -- that is taken into account and the toggle panel is not rendered.

I guess the problem is knowing when the open/close state of the toggle panel is set/decided, and what influences this process.)

Another thing I would try is binding the open parameters to a controller property. Something like opened="#{similarProblem.isOpen}". And then obviously have those all set to false beforehand.

Awesome, this worked! Didn't think about this, thanks a lot :-)
