MenuService WorkbenchContext/TrimmedWindowImpl [message #1830666]

Hi
when I run my e4 product, on startup I get the following error message without further information:

MenuService: WorkbenchContext: org.eclipse.e4.core.di.InjectionException: Unable to process "MenuService.myPart": no actual value was found for the argument "MPart".
MenuService: TrimmedWindowImpl (ch.eugster.herakles.app.window.main) Context: org.eclipse.e4.core.di.InjectionException: Unable to process "MenuService.myPart": no actual value was found for the argument "MPart".

I tried to debug to find the problem but without success. What am I doing wrong?
Christian

No clue what you are doing wrong, but got some clues where the error comes from.

The error is raised by MenuServiceCreationFunction, this context function is in charge of creating the EMenuService/MenuService. The MenuService has a field 'private MPart myPart' which is being injected. Apparently, you are requesting a EMenuService in a context where no MPart is available. The context that is used is 'WorkbenchContext' which I can imagine that it doesn't have a MPart.

Are you using EMenuService to create menus Controls that are not within a MPart?
