ACTION_ARRANGE_ALL: how to execute it from custom Action? [message #521920]

Hi,

I need to execute an 'ARRANGE ALL' action on a diagram, called by a own custom action (essentially an Open Diagram Action); this is the code:

ArrangeAction arrangeAction = ArrangeAction.createArrangeAllAction(page);

arrangeAction.run();

but I got a NullPointerException. Maybe I'm calling and executing the Action in a wrong way?

Thanks for any help, regards

Giovanni.

You'll have to debug into your arrangeAction to find out what the NPE
is. For example, are you passing in a null page?

Hi Paul,

no, I'm sure the page I'm passing it's not null, I retrieve it with the following code:

IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();

I have debugged the code, but I'm unable to find the NPE source.

Any suggestion?

Thanks,
Giovanni.
