What do you mean when you say "I keep getting null returned for this call"? Do you mean you get NullPointerException exception? If so, can you please provide the exception stack? Or, did you see any error log in the console?

I know nothing about the Extensions Workshop. I am just trying to figure our the problem from the basic technical view.

2. I am not sure I understand how I can determine exactly what services I require for what I want to do.

2. I am not sure I understand how I can determine exactly what services I require for what I want to do.

So one challenge I am having is in creating the Aspect Editor.

I keep getting null returned for this call:
PlatformUI.getWorkbench().getActiveWorkbenchWindow().run(true, true, new RunnableWithProgress() {....

Is there any reason for why this happens or how to avoid? I am following the pattern in the getWorkItemsType call of the 3.0.1 Extensions Workshop labs which is consistent with what I see in the out of the box preconditions.

Thanks.

Same here Sam. Most of my material is also from helping people.

I hope we can pull more material together to provide more workshop material. It is just a matter of how much time I can spend.

Thanks so much for contributing!
