@Daniel: thanks a lot - that did the trick! > I'm not sure I really understand what you want to do here Fyi. I´m working on a travel site, where I need quite some different travel search forms. Whereas some fields in these forms are common(eg. number of travelers, destination,...) some fields need customization - like default travel start date. So my idea was to instantiate derived forms corresponding to the site sections I would place them at; think 'SummerSearchForm' in views related to summer tours and 'WinterSearchForm' in skiing season pages and so forth. I can do that now - thx again! : )
@ Bruno Thx for the comp.lang.py tip ...definitely will have a look!
