I am encountering a strange behaviour of the selection service in my eclipse view/editor. The following code ist taken from my comand handler to open an editor when double clicking in the treeviewer of my view.
//getSelection via SelectionService
IWorkbenchWindow w =  HandlerUtil.getActiveWorkbenchWindow(event);
ISelectionService sels = w.getSelectionService();
ISelection s =  sels.getSelection();
if (s!=null && !s.isEmpty() && s instanceof IStructuredSelection && ((IStructuredSelection)s).getFirstElement() instanceof Event){

An here comes the funny thing: "s" is sometimes null after processing the line. To doubleclick and open the first editor works always fine. To open a second editor via another double click results in "s" beeing null. When I start the debugger and set a breakpoint befor the "if", everything works fine. When I do the same thing without breakpoint even in the debugger mode the selection service returns null again.

Is there annyone out there with an idea to help me?

Greetings Florian
