I'm a little bit frustrated, because googlemapstv stores values "Ja" / "Nein" into the DB for every combo-boolean.
I found out, that an inopt_ is rendered different than a prop_, which is used in googlemapstv.
An inopt uses a hidden field for the boolean value, but a prop_ doesn't.
Could please anyone help me, at least gimme a tip, where I have to hack

?
