sample eclipse application

There seems to be a regression in 4.13 (versus 4.12) related to menus enable status. Please have a look on the attached sample application: if you open the drop-down from the first item in the toolbar, you will see that the second menu entry is disabled, but this is not the case in 4.12. Could be this related to this case: https://bugs.eclipse.org/bugs/show_bug.cgi?id=547050 ?

What "seems" means: did it worked in 4.12 or not?

Probably not, reverting the change doesn't fix your example.

May be bug 552361?

You could help if you would check out platform UI code and bisect to the commit that breaks your application.

no it works in 4.12 (if you switch between target platforms you can see that in the sample)
But it doesn't work in 4.13

But there is something weird..
Under Linux the menu items never enabled what ever you do.
Under Windows the menu is first disabled, but if you click on it, they are suddenly getting enabled
And i think under OSX they are just enabled all the time...

Bug 20298 and Bug 30423 are related, I don't think it is Bug 552361.

Something changed that made the UI widgets to only be created when the become really visible. The current code checks for the UI widgets for the sub-menus to be available, which is no longer true as they are only created at the first time they are showed.
