Manually triggering a class with injections? [message #955072]

I have a class, which get a MApplication injected. It is a Handler. I want to trigger the Handler's methods manually.

Problem:
When I instantiate the Handler manually from another class - the MApplication is null. The class which I trigger the Handler from allready has an MApplication injected, so it is not a lifecycle problem.

Question:
How can I trigger a method in a class, which has @Inject annotated methods?

Have a look at org.eclipse.e4.core.contexts.ContextInjectionFactory

Thnx, the following Injected everything from the current iEclipseContext into the new Object.

		ManipulateModelhandler man = new ManipulateModelhandler();
		
		//inject the context into an object
		//IEclipseContext iEclipseContext was injected into this class
		ContextInjectionFactory.inject(man,iEclipseContext);
		
		man.execute();

I think you should invoke ContextInjectFactory.invoke method with @Execute as parameter

java eclipse Search

Even though I'm not aware of what you are trying to achieve, creating handlers manually and calling @inject methods with CIF does not sound the right approach except in some really advanced cases IMHO.

Anyway, getting to your question the CIF.invoke will invoke annotated methods for you.
