Hi,
I'm designing a RCP application with views and editor parts. In some part,
i'm using the SelectionService mechanism and i set SelectionProvider
object on their site "getSite().setSelectionProvider(provider)".
In a other hand, i'm using the "org.eclipse.ui.menus" to display popup
menu with command. Each command refered to a
"org.eclipse.core.expressions.definitions" extension point to test if we
display the command or not. I use the expression "selection" and it seems
to do not work correctly. At the initialization of the RCP, the
"selection" is not updated and the item associated to the command is not
displayed in the popup menu.
I need to re-activate the part to make it work. I've seen that there are
two SelectionService which are declared at the beginning :
PageSelectionService and WindowSelectionService. The
WindowSelectionService does not call its setActivePart() method at the
initialization of the application so the provider is not set for this
service. So the selection is not updated for the
"org.eclipse.core.expressions.definitions" extension point. And i think
it's the reason why it is not working properly but i might be wrong.
If someone knows a way to make it work correctly without reactivating the
part everytime we have to launch the application, i would appreciate it.
Thanks.

Hi,
I've used the "activeMenuSelection" and it works well, thanks you Paul and
Tom. But i'm trying to understand how the "selection" works. I have a view
with a viewer which contributes to the selection service as selection
provider. And i have created another view which listens to this provider.
I would like to display in this view the same menu items which appear in
the pop up menu of the first view when i do a selection in that part. I
would to use the extension point "org.eclipse.expressions.definitions"
where i defined the rules which allow to display the menu item or not. But
this time, i use the "selection" variable to know the selection in the
first view. And it does not work properly, i need to re-activate the first
view to make it work correctly. I'm wondering how can i do this correctly.
Moreover i use in the first view a "dynamic selection provider" because i
have several viewers. But i don't think it is linked to my problem.
Maghen.
