Bug 28277 Double-clicking in the Types view refreshes decorators
In build I20021210, with CVS decorators turned on, in the Java browing perspective, if I double click on a class in the Types view, the decorators in the view undergo a visible refresh (i.e. they go away and then reappear).

ArrayList result= new ArrayList(elementsLength);
		for (int i= 0; i < elementsLength; i++) {
			Object element= elements[i];
			if (fViewer.testFindItem(element) == null)
				result.add(element);
		}
		return result.toArray();
	}
	private void postRemove(final Object element) {
		postRemove(new Object[] {element});
	}
	private void postRemove(final Object[] elements) {
		if (elements.length <= 0)
			return;
		
		postRunnable(new Runnable() {
			public void run() {
				Control ctrl= fViewer.getControl();
				if (ctrl != null && !ctrl.isDisposed()) {
					ctrl.setRedraw(false);
					if (fViewer instanceof AbstractTreeViewer)
						((AbstractTreeViewer)fViewer).remove(elements);
					else if (fViewer instanceof ListViewer)
						((ListViewer)fViewer).remove(elements);
					else if (fViewer instanceof TableViewer)
						((TableViewer)fViewer).remove(elements);
					ctrl.setRedraw(true);
				}
