ViewPart's @PostConstruct createControls() not called [message #1001493]

Hi,

I defined a MPartDescriptor in my Application.e4xmi, then in a Handler I get an EPartService injected which I use to createPart() and showPart(). I can then get my actual ViewPart impl object from mpart.getObject(). The problem I have though is that my ViewPart class's createControls() is never called. It is annotated with @PostConstruct (the ViewPart class was created with the Eclipse 4 ViewPart wizard). Any ideas how I can get the method to be called? (I can't call it myself because I don't have the parent Composite that must be passed in...)

Hi

I add the part to its new parent part stack, like this

	    MPartStack stack = (MPartStack) modelService.find("org.eclipse.e4.primaryDataStack", appl);	    
	    MPart part = partService.createPart("...");
	    stack.getChildren().add(part);
	    partService.showPart(part, PartState.ACTIVATE);

If @PostConstruct is not called please check if the bundle in question
does an import-package for javax.annotation, do not use require bundle!
You need to have a import-package javax.annotation 1.0.0

@Tom

I am not familiar with the issue of required vs. imported javax.annotation. Is there a bug or some other documentation where I can read a little more about this?

Thanks,

JD

ps. - I haven't run into an issue, but I want to make sure I don't Smile

Thanks, Frank and Tom. I was missing the javax.annotation package import.

IIRC there's even an FAQ,
