Bug? having troubles to render tree...
<h:form> <rich:panel> <rich:tree id="tree"> <rich:treeNodesAdaptor> ... </rich:treeNodesAdaptor> </rich:tree> </rich:panel> <rich:simpleTogglePanel id="panel"> <a4j:commandButton type="button"> <a4j:support event="onclick" reRender="tree, panel" /> </a4j:commandButton> </rich:simpleTogglePanel>
The tree is displayed when the page loads... but on the button's click this exception apears in the screen (the button's action runs normally):

This only occurs on the first click of the button... after that none exception is shown... and the button works just fine...
Any clues?
Thanks in advace.
