MainMenu isn't persisted [message #1066189]

Hi,

My RCP (on 4.3 in compat mode) doesn't persist the window's main menu in the workbench.xmi. So the first time I start my RCP (when no workbench.xmi is available) the menu is shown as it should. After a restart the main menu isn't there, MTrimmedWindow.getMainMenu() == null.

The RCP consists of seven fragments that are included in the application. The Application.e4xmi only has a MTrimmedWindow with a Trimbar, a PerspectiveStack and the MainMenu (more or less Smile

).

Did anyone else experience something like this, or has a hint?

Best regards,
Bastian

Set a breakpoint in setMainMenu and find out from the call stack when it is made null.

Hey,

thanks for your answers. This is exactly my problem as well. So did you find a solution for it, since the case is closed? I also had a look at this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=388808 which seems to be the same.
My RCP uses all the id's of the Legacy.e4xmi, so I don't know, if that's the reason, it isn't shown.

Unfortunately I'm not able to open the application live editor (with Alt+Shift+F9) in Eclipse 4.3 to have a look at differences between my model and Eclipse's. Is there another way to open the live editor, or do I have to unlock something?

Best regards
Bastian

To open the live editor do a CTRL+3 and type live editor. If it shows up there and you can open it please file a bug on e4/tools regarding the unability to open it through the shortcut.

Hi Bastian,

I tried to make a cut down example with the LegacyIDE.e4xmi but i did not succeed.
Even when I take the original LegacyIDE.e4xmi and only add a single menu entry, the menu disappears with the second start.

Hi,

thank you for your answer. Well that's what I experienced, too. I don't see anything different to the original Legacy.e4xmi.
I "solved" this by contributing the menu in code. The menu doesn't need to have a persisted state and it is very small, so it's no problem to create it in code. But of course, this is not a real solution.

Thank you for your help
Bastian
