Erik van Oosten commented on WICKET-214:
----------------------------------------
The situation would already be improved a lot if the javadoc would make it
clear that it is not possible to add multiple behaviors to the same event.
Yet another option is to provide an aggregation behavior. Something that would
allow you to merge 2 behaviors into 1. I am not sure how this could work.
I am not familiar with Wicket.Event (a 1.3 feature?).
> Call all behaviors attached to the same event
