Question

I have a ContentProvider for a Tree view. There I add some actions that can be performed on an item of the tree. The method looks like this:

private void makeActions() {
   action1 = new Action() {

   @Override
   public void runWithEvent(Event event) {
      System.out.println(event);
      System.out.println(event.data.getClass());
      //How can I find the caller of runWithEvent?          
   }    
};

How can I find the object of the tree that has caused the call of Action#runWithEvent?

Consider using the new Command API instead of the older Action API. In the new API, you can easily access the relevant information in the handler for the command.
