[news.eclipse.platform.rcp] Controlling visibility (menu/view/perspectiv

[nebulour@xxxxxxxxx (Brian)]

I want to allow plugins to contribute to the menu bar, perspectives, 
views, etc. but these items should be conditionally available.  For 
instance, a user logs in to the app and based on their permissions they 
see certain menu items, views, and perspectives.

I was hoping to do this using declaratives but there are bugs and I'm not 
sure if that would be possible anyway.  How do I do this sort of thing?  I 
did a little test for a perspective/view/command plugin and they all just 
display.  Also, once  I get this figured out, how do you enable/disable 
menu items based on what perspective is shown?

Thanks.
