Hi! Thanks for spending your time for helping me.
I have the followind problem. I made a View which is extension of
org.eclipse.ui.navigation.viewer. My viewer works fine when it's ran as
Eclipse Application, however when I try to run it as Product I see the
following stack trace :
org.eclipse.jface.util.Assert$AssertionFailedException: null argument;

I wonder why the argument is null and how can I set it?
Thanks in advance

Hi Nenko,
If you're trying to use the Resource extension in an RCP app, you will
need org.eclipse.ui.navigator.resources as part of your RCP app, and its
dependencies. Otherwise, if you're just trying to use the
Common Navigator framework, you do not need this plugin.
-MDE.
