Steps To Reproduce:
1. Add the Cut action to the toolbar (for me done in the ApplicationActionBarAdvisor):
   
   private IWorkbenchAction cutAction;
   ...
   cutAction = ActionFactory.CUT.create(window);
   register(cutAction);
   ...
   toolBarManager.add(cutAction);

2. register the TextActionHandler for a text widget:
   TextActionHandler textActionHandler = new TextActionHandler(this.getViewSite().getActionBars());
   textActionHandler.addText(myText);

3. Now open the application, put some text in the text widget, mark it and push the icon 'Cut' from the application toolbar. The button gets disabled and the cut-action is not done.

More information:
I'm using the TextActionHandler in a non-IDE application. The reason for the bug seams to be the following:

1) The text widget gets activated when the user typs some text in the widget.
2) The listener SWT.Deactivate is fired when the user pushes a button from the toolbar. activeTextControl gets null and the button gets deactivated.

I have modified the following code in the class TextActionHandler:

    private class TextControlListener implements Listener {
        public void handleEvent(Event event) {
            switch (event.type) {
            case SWT.Activate:
                activeTextControl = (Text) event.widget;
                updateActionsEnableState();
                break;
            case SWT.Deactivate:
                //do not set the active widget to null
                //activeTextControl = null;
                updateActionsEnableState();
                break;
            default:
                break;
            }
        }
    }

I do not know if this could solve the problem, since I haven't tested it very well.
