Broken popup menu with compatibility layer [message #1357433]

We have switched to Eclipse 4.3.2 and use the compatibility layer to run our Eclipse 3.7 based product. In one view I have a broken popup menu. It gets populated, but with too much entries and no labels. I think those are all dynamic menus with CompoundContributionItem. Are there any known problems with that?

Hello,

I also had some problems with menu and popup items, which were not visible. There are still some bugs concerning menus in e4 (e.g. https://bugs.eclipse.org/bugs/show_bug.cgi?id=383403). You can try to have a look at Eclipse 4.4.

You could add the popup menu programmatically. This still works fine. I know that this is not a nice workaround, but solves the problem, if you are in the compatibility layer.

Already tried 4.4M7, but nothing changed.

I did a little debugging! The dynamic menu contribution has a visible when condition. The PopupMenuExtender tries to fill this menu contribution before the visible when condition gets evaluated. In this case the implementing class is expecting something different and therefore throws a NullPointerException. In eclipse 3.x it was handled differently. The visible when condition was evaluated first and in this case the getContributionItems method was never called and never threw an exception. Is the new handling implemented on purpose or is it a bug? When handling changed I need to review all my dynamic menu contribution implementations and make them more failsafe.

By the way: You see the NullPointerException only with activated trace options!
