I have a custom button class where I have the onClick() method send a query to a facade in my business-tier. This works. I have the result set up in my business tier to call a callback method with the results. This works. The problem is that when I try to reference or instantiate any of the ZK components (ie Label l = new Label("Hi");) I get a NullPointerException. I am guessing this is because the callback has no reference to the ZK session I was in when I clicked my custom button.
>From the User Guide I see there is a ZK AU Engine for handling asynch events.
Is this what I need to handle my situation and to update my ZUL controls when I receive an asynch message/event?
Any samples would help.
Thanks

ZK components can be handled only in an event listener. It works fine as long as you stay in the same thread as the event listener. For long operation that you prefer to execute in background, please take a look at User's Guide (pp 33).
Jim, please post the stack trace. I would make it more readable (for other developers). Thanks.

Implement com.potix.zk.ui.event.EventListener and register it with Component.addEventListener.
