[news.eclipse.platform.rcp] Re: Where to activate a default context

[Jochen Mader <jochen@xxxxxxxxxxx>]

I already tried that but for some reasons the visibleWhen for my menu
still gives a false.
I contributed a new menu to the mainmenubar. that menu should
appear/disappear depending on the context that is currently active.
It works if I activate the context from the handlers but nowhere else.
