Re: Strange Exception

Wed, 27 Feb 2008 09:34:04 -0800 

No (don't know what it is).
I think maybe this problem was caused by the RunJettyRun plugin picking up my wicket-1.3.0 jars that I had forgotten to delete from my project. I did not reference those jars, but the files where still in my project directory. 


I did some general "update all plugins" and project cleaning. Then the 
problem disappeared. There wasn't much to clean, but I did have that 
older version of wicket still in the project directory. (Must have had 
it there since 1.3.1 was released.)

Hi,

 I (sometimes) get a strange Exception. You can see the stacktrace in the
 attached file.

 The problem appears (sometimes) when I submit a form. Just displaying
 data/pages is never a problem.

 At first glance it seems I get a ClassCastException when doing

     public static BLAppSession getCurrent() {
         return (BLAppSession) Session.get();
     }

 Debugging the code I cannot see anything (obviously) wrong with my
 Session subclass. Something else must be the actual problem. What does
 this mean:

 Use Wicket 1.3.1.
