[news.eclipse.platform.rcp] Customize Perspective Dialog not working

[darragh.mcgeown@xxxxxxxxx (Darragh McGeown)]

I've been trying to implement the 'Customize Perspective...' in my RCP 
application and have been successful in getting the customize dialog open 
but after making edits to the menus and tools the OK button does nothing. 
It doesnt apply the changes or close the dialog. Is there something I need 
to do or do you have any reference material?

Im creating the 'Customize Perspective...' action as follows:

customize = ActionFactory.EDIT_ACTION_SETS.create(window);

Thanks in advance,
Darragh
