if I implement the methods getImage(Object) and getText(Object) for a rule in MyDslLabelProvider the specified image is only shown in the outline view and for the references in the proposals window. But the icon/image is not shown for the rule itself. For example, if I define an entity the image doesn't appear in the window that displays completion proposals when content assist was invoked to get the proposal with "entity" string.
Is there a trick to show the icons for the rules in the proposals window?
