communicating to a hidden view [message #467371]

Hi,
I Have an Rcp application with 4 views. Each view communicates to the other view. Currently i cannot close any view. I would want to improve it such that i can close any view and open it from Show View (I Have achieved this). But once i close a view and make some action in one of the opened view, which should communicate to the closed view. Naturally this will throw an error.

How can i handle this problem, as i see the same behaviour is handled in eclipse also (i.e. Navigator view and outline view.).

Thanks and Regards
Byre

How is your communication done?
You should use a event approach and when closing a view simply
unregister all listeners to that view. If you are simply interested in
selections use the ISelectionProvider interface and set the selection
provider on your ViewSite.

Well eclipse uses the selection provider to communicate between the
views. See above for details.
