Hi,

I am trying to implement Project Wonder's AjaxTabbedPanel and AjaxTabbedPanelTab in my application by following the Wonder Ajax Examples from the link http://webobjects.mdimension.com/cgi-bin/WebObjects/AjaxExample.woa/1 . But after added these AjaxTabbedPanel and AjaxTabbedPanelTab in my component's html and wod files then my page is not loading, getting the following exception:

------------------------------------------------------------------------------------------------------------------------------------

23848 [WorkerThread15] WARN NSLog - <com.webobjects.appserver._private.WOComponentRequestHandler>: Exception occurred while handling request:

------------------------------------------------------------------------------------------------------------------------------------

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;

}

------------------------------------------------------------------------------------------------------------------------------------

Thanks,
Raghu.
