Martin Grigorov commented on WICKET-1429:
-----------------------------------------
Yes, this is a good idea. Please create a new ticket and attach a quickstart to
it to save us some time.
It wont work in all cases though. It is the same problem as
Component#onInitialize() solves - when adding the behavior to the Form the Form
itself may still not know its parent and thus there is no way to know that it
is nested or not. So we can do this check as a best effort in DEVELOPMENT mode.
> AjaxFormSubmitBehavior doesn't work well with nested forms
