Hi Lutz:

I've answered this on bottom of my message:

"In the case that you want to be notified about not just the change, but the value itself, then you need to use the "assign" event and bind to it, so you can get the "value" passed by parameter."

So you need to create an assign event for yuor property then BindEvent the Assign event.
