I have a toolbar on my view with a delete group button.
The view contains a treeviewer, with groups & persons. When you click on a group an editor opens with all the information it containts.
Now I want that when you click on the delete group button, that the group you last selected gets deleted. I have written my handler however I don't know how to get the last selected group into my handler, when I call the command it should know wich group to delete. How do I do this?
