Igor Vaynberg commented on WICKET-3097:
---------------------------------------
thanks for the testcase pedro, ive cleaned it up a bit and committed.
re 1.4 we decided not to apply it because it touches some very fragile parts of
wicket and we would rather not make 1.4.x any less stable. the chances of this
happening in 1.4.x are much slimmer then in 1.5. it requires a combination of
metadata/temporary behavior/callback behavior all used within the same
component. 1.5 uses metadata on every render so there the problem is a lot more
prominent.
> isTemporary behavior and ajax behavior together crashes with
> WicketRuntimeException: Couldn't find component behavior.

> My scenario:
> 1. Component has 2 behaviors: first is temporary and second is ajax behavior.
> 2. Url for Ajax behavior contains behavior's index (e.g.
> ../page?1-1.IBehaviorListener.1-form-text)
> 2. Temporary behavior is removed in detachBehaviors method.
> 3. Ajax request is invoking ListenerInterfaceRequestHandler and it's
> looking for behavior on non-existing index
> This scenario causes error on wicket 1.5-M2.1
