Rainer,
For your first question you say that you have the google key in a hidden
form field. So that means you can do:
googleWrite(MyCFC, 'MyKind', 'MyKey123');
What's the trouble? Is it that you would prefer to do something like:
MyCFC.setGoogleKey('MyKey123');
MyCFC.googleWrite();
So that you don't have to specify a kind?
