EMenuService Discouraged access [message #1358951]

I configure Popup-Menus in the e4xmi and bind them with the EMenuService to tables, trees and other controls. This works fine as long as I don't dispose such a control with a defined popup menu from the e4xmi.

But the EMenuService is marked as discouraged and should not be referenced. So what should be used instead, when I want to use the popup menus from the e4xmi? I researched several tutorials and forums but didn't find another opportunity.

The reason it is 4.3 is that we didn't want to make it API and this was
a good choice because we had to relocate it in 4.4 where it was promoted
to be API.

So yes EMenuService is what you are looking for but be prepared to make
a small adjustment when switching to Luna!

It's nice to read that the EMenuService will become API.

I have an additional question:

When I register a context menu to a widget (e.g. Tree), and after some time this widget gets disposed and recreated again, the menu is not visible any more, if I register it again. Is this a bug or do I have to guarantee that the widgets stay alive to keep the context menu?

This is a tricky task, if you have tables or trees with changing columns. This could be a bit easier by disposing and recreating them.

This certainly sounds like a bug but looking at the code I don't see why
you should not get a menu when disposing & recreating
