> ClassCastException in StackingTreeModel.java:137 
> Method doSetupKey throws classCastException for one of the scenario.
>  
> Steps:-
> Search items so that we get Tree(richfaces) list on page.
> Delete the one of the node from tree (ajax delete)
> After that we tried to reset the search parameters (They are in different a4j:region than the tree) by clicking on Reset button
> which means we had to rerender tree for reset operation.
> While rerendering the tree we got class cast exception. at line 137.
>  
> Following is the code we fixed in our project.
>  
> protected StackingTreeModel doSetupKey(Iterator<Key> keyIterator, Iterator<StackEntry> entriesIterator, FacesContext context, Object modelKey) {
>  if (modelKey != null) {
>   if (!setupModel(modelKey, context)) {
>    //no key is available
>    leaveModel(getRoot().stackEntries.iterator(), null, context);
>    return null;
>   }
>   
>   //TODO what's here?
>  }
>  
>  if (keyIterator != null && keyIterator.hasNext()) {
>   //Patch added by Atul
>   Object obj = keyIterator.next();
>   if(obj == null || !(obj instanceof Key)) {
>    leaveModel(entriesIterator, null, context);
>    return this;
>   }
>   Key key = (Key)obj;
>   //Patch ends by Atul
>   //Following is orginal code commented by Atul for above patch. 
>   //Key key = keyIterator.next();
