Empty dialog output
Objective: dialog produces output on OK if any text entered, else bang.
Approach: load a register with some token; open dialog; if OK without entering text, bang register to output token and route token, else output input thru register.
Issue: the routed token does produce a bang, but it does not trigger the message. How can this be?

MAX doesn't seem to handle null messages ? Workaround :
The old thread was about banging an emtpy message being like whipping a dead horse, but the fundamental issue is the same. The reason my previous patch doesn't work is that the output of the route should be fromsymbolled. Duh.
This works:
Only thing is, it will also output the 'None' message on Cancel. You'd gave to gate that.
