Clint Popetz commented on JBSEAM-3195:
--------------------------------------

I'm not sure how this would work.  WickeComponents aren't really full-fledged seam components; their lifecycle is not managed by Seam, and they aren't bound to a context.  So while I could have WicketComponent register methods marked @Observer with Init's list of observers, there's no way to find the actual instance of that component to invoke the method upon at event time.

The only path towards this I could see would be to actually make Wicket component instances live in seam's session context (because they do have a session lifetime in Wicket's pageMap.)  This could be done, but afaict the only benefit would be @Observers, because I don't think you'd ever want to inject an instance of a wicket component into another object.  (It would be like injecting a JSF UIComponent subclass, which I see no use for.)

I'll leave this issue open to hear other's thoughts on it.
