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:
SEVERE: there was an error cleaning up target

Use Wicket 1.3.1.
