Overview: In a context menu, there is an action whose enablement state depends on an objectState. Using this action changes the object state in such a way, that the state of the action must change. However, the state of action is not updated until the user changes the selection and re-selects the same selection.

Steps to Reproduce:

1) Create a view with a viewer (table, tree etc).
2) Create a class 'TestClass' which implements IActionFilter. It should have a single state, for example: 'isActive' (false by default).
3) Put an object of type 'TestClass' in the viewer.
4) Create a org.eclipse.ui.popupMenus extension. Add a viewerContribution to the created view. Add an action with the following enablement:
   <enablement>
      <and>
         <objectClass
            name="TestClass">
          </objectClass>
          <objectState
            name="isActive"
            value="false">
          </objectState>
       </and>
    </enablement>
5) Implement the action which changes the state 'isActive' to true when it is used.

Actual Results: Run the program. Right click on the object and use the action. The isActive state will be changed to 'true'. Right click on the object again. The action will be still enabled even though the state of the object is changed.

The state of the action only updates if the selection is changed and then the object is re-selected.

Expected Results: Since the action enablement is based on the objectState, the state of the action should change if the object state changes.

Maybe the enablement status can also be updated after an action is used or when the context menu is opened?
