Re: [Wicket-user] Schizophrenic Components (that suddenly change their Variation)
I haven't read it in detail, but variation is not meant for doing that
kind of stuff (though it should work). Rather, use panels and
replacement (switch the panels).

Re: [Wicket-user] Schizophrenic Components (that suddenly change their Variation)
I guess it is because Wicket caches the Markup associated with a
Component. Wicket assumes that the associated Markup does not change
once loaded, except if you change the markup file content itself,
because the cache will be cleared than. I guess I would create two
separate Panels for LoggedIn and LoggedOut and either add() the one or
the other to the container.
