Bug 119849 Open Type's Window Working Sets setting isn't remembered
Using the the build "I20051206-1200" the "Open Type" dialog doesn't remember the setting "Window Working Sets" for the "Select Working Sets..." option. The other settings are remembered :/ Example: I have a clean workspace, create two projects (A and B, w/ one class each: A and B), assign to two working sets (one containing A, on B) , select project "A" as window working set, selct "Open Type", select "Window Working Sets" in "Select Working Set..." - everything is fine. I close the "Open Type" dialog, reopen it, and the setting is back to "No Working Sets"

fWorkingSetListener= null;

		fChangeListener= null; 
		
		super.dispose();
	}
	
	/**
	 * @return Returns viewer filter always configured with the current working set. 
	 */
	public ViewerFilter getWorkingSetFilter() {
		return fWorkingSetFilter;
	}
		
	/*
	 * Called by the working set change listener
	 */
	private void doPropertyChange(PropertyChangeEvent event) {
		String property= event.getProperty();
		if (IWorkingSetManager.CHANGE_WORKING_SET_NAME_CHANGE.equals(property)) {
			fChangeListener.propertyChange(event);
		} else if  (IWorkingSetManager.CHANGE_WORKING_SET_CONTENT_CHANGE.equals(property)) {
			IWorkingSet newWorkingSet= (IWorkingSet) event.getNewValue();
			if (newWorkingSet.equals(fWorkingSet)) {
				fChangeListener.propertyChange(event);
			}
		}
	}
