Hi Chuck,
WOActionResults res = super.invokeAction(aRequest,
aContext);
...
return ((WOComponent)res); // Exception
occurring at this line-151.
I have changed the casting from WOResponse to WOComponent, and now the
error in the Session invokeAction(. .) method is not occurring. But
the exception (InvokeTargetException) is occurring in the my
Application's dispatchRequest(.) method, getting the following
exception:
Also I see a NullPointerException from the AjaxTabbedPanel class at
the end of the following exception:

Perhaps if you cast correctly? The issue is with your code, not
AjaxTabbedPanel.

Hi,
I am trying to implement Project Wonder's AjaxTabbedPanel and

My Application and Session classes extends ERXApplication and
ERXSession classes.
Any help would be appreciated.
Also adding my Session class invokeAction method code:
------------------------------------------------------------------------------------------------------------------------------------
public WOActionResults invokeAction(WORequest aRequest, WOContext
aContext) {
WOElement element =
(WOElement)requestLookup.objectForKey(aRequest.uri());
if ( element == null ) {
WOActionResults res = super.invokeAction(aRequest,
aContext);
try{
element = ((WOComponent)res).template();
}catch(Exception e){
e.printStackTrace();
return ((WOResponse)res); // Exception
occurring at this line-151.
}
if (res!=null && element != null && !
isReportMillComponent(element)) {
requestLookup.setObjectForKey(element,
aRequest.uri());
}
return res;
}
else if ( element instanceof WOComponent ){
((WOComponent)element).ensureAwakeInContext(aContext);
return (WOComponent)element;
}
return null;
}
