I had trouble to get listShuttle work. My source list contains some entity beans, the listShuttle does show up but can't select anything. The only button enabled is "Copy All" but it doesn't work either.

Then I tried a simple listShuttle which has strings in the source list, the result is same.

Here is the simple code

<div class="oppsearch"

 targetValue="#{loadGroupAction.targetStrs}"
 var="str"
 listHeight="300"
 listWidth="300"
 sourceSelection="#{loadGroupAction.sourceSelection}"
 targetSelection="#{loadGroupAction.targetSelection}"
 sourceCaptionLabel="Source List"
 targetCaptionLabel="Target List">

 </h:column>
 </rich:listShuttle>
 </a4j:outputPanel>
 </a4j:form>
 </rich:simpleTogglePanel>
</div>
