Could you show us some code please? "Outside the Wicket 
application context" sounds strange, does it mean another 
thread?

Just about everything that you do with Wicket components 
needs a couple of ThreadLocal variables initialised, the most 
important of them being the Application (with Application.set() ). 
But to know how to fix your issue exactly we need more data.

WicketSessionFilter might help.

Best wishes,
Timo
