Hello,
I have the following problem: I have an ext.pt.-declared
IViewActionDelegate (concretely: "org.eclipse.ui.popupMenus"),
which works besides one issue: Regrettably the actual action title
depends on the current selection. This is no problem once
the contributing plug-in is already active, when the selection
takes place. The problem is: The first selection in this view
does not necessarily activate that plug-in, so at this place
only the static ext. point caption is presented. This cannot
be reasonably set to the correct title without analysis of
this selection. This can also not be done by the view itself,
because it also is generically written.
Now its clear, that the action representative created by
the menu framework does have to react on selections (it allows
prefiltering possibilities, which are ext.pt. declared). There
exists name filters, but regrettably the name filter does not
have the action as argument, so that I could change its title.
Does there exists any similar approach, where I can reliably
register a selection observer configurable by the
"org.eclipse.ui.popupMenus" viewer contribution point?
I actually would hate to need to register the corresponding
plug-in as StartUp plugin. It would be sufficient, if it would be
activated when the first selection in the corresponding viewer
takes place. Since this viewer is in its own plug-in and must
not depend on the other plug-in I hope it is possible to reach
the wanted effect with a special option of the
"org.eclipse.ui.popupMenus" ext. pt.
Any ideas welcome!
Greetings from Bremen,
Daniel Krügler

Try to activate your plugin using:
Platform.getBundle("your.plugin.id").start();
during your first selection.
