if you want to pass these variables to your view, use
Event.setValue("formevent", "value1"); in your Handler
and
Event.getValue("formevent"); in your view
I've just never tried to pass any variables through renderView, and i
didn't find any documentation on that.
Since the decision or the values of the variables occur in the view at
the moment I call the "include" function, and not the handler.
(probably bad design) I will review it and re-design it.
