Just a quick note on the side, I experienced this now under Wicket 1.4. I have a component implementing my custom specialization of IRequestListener. The decision logic in RequestCycle.urlFor about which IRequestTarget gets selected for the encoding leads to BookmarkableListenerInterfaceRequestTarget unless one of the following:

- Component.getStatelessHint is overwritten somewhere in the class hierarchy of the concrete Component class with return false
- the Page that contains the Component happens to be known as stateful
- the Page that contains the Component is not bookmarkable

> behavior#getStatelessHint() can check if behavior implements IBehaviorListener and if it does return false from stateless hint. also InvalidBehaviorIdException can point to getstatelesshint() being true when it should indeed be false as a probable cause for the error.
