The problem occurs when using a theme derived from the "Business" theme applied to a RAP application that uses standalone views. When trying to hide a view, the ViewStackPresentation.removePart() method tries to remove the button associated with the ViewPart, but there is no button available. As such, the following line: ( ( Composite ) object ).dispose(); throws the NPE since object is null. As a side effect, the view that was supposed to be removed never goes away since the remainder of the method is skipped. I put a null pointer check on the above line prior to execution and solved the immediate problem, but the method could probably use a bit of refactoring to make the cause of the condition a bit clearer.
