Hi
I have an e4 app with perspective and Parts in PartStack. I add a Handler to a part and inject this part in the handler class. Running the app I get an exception:

org.eclipse.e4.core.di.InjectionException: Unable to process "ResetHandler.part": no actual value was found for the argument "MPart".

I am not yet very close to injection, so i appreciate any hint, Thank you!
If I inject the part in the execute method like this:

@Execute
public void execute(MPart part)
{
}

it does work.
Christian

Solution: It seems that MPart is only available if the handler is assigned directly within an MPart in the application.e4xmi
