Bug 110998 [Problems] Remove the working set selection and switch to using global working sets
M2 We need to remove the working sets option in the filter and switch to using the current list of working sets. We should move this to a preference that says only "Use Working Sets"

		for (int i = 0; i < subTypes.length; i++)
			addAllSubTypes(types, subTypes[i]);
