Hello,

I'm writing my own connector for HP Quality Center... but I have a NPE when opening the task editor (see below) when I set the needsSubmitButton flag to true in the AbstractTaskEditorPage...

In the following line, the toolkit is null :(

submitButton = toolkit.createButton(composite, Messages.TaskEditorActionPart_Submit + " ", SWT.NONE);


Any idea??

Best Regards,

Tom

About time! What version of QC do you support? How does it work (COM?)?
And most important, where can I get it?

Cheers

I would guess that your page factory does not return PRIORITY_TASK in
getPriority(). Still, this should not be happening. Can you file a new bug:
