Well, I don't want to bother you - and I really reviewed a lot (nearly all, I think) of the mails in the list and even the HOWTOs, but ... I still have no idea how to make a selection property properly. I'm making a ZClass with a property-sheet, in which there should be a property, that has a value you select from an ordinary select field. I generated it with type "selection", name "Status" and value "status_liste". (the error message told me to give a variable name as a value) And now my question: where do I fill "status_liste" with what kind of values? I'd love to fill it with something like: {'status1':1,'status2':2,'status3':3} Big hurdle or just my incompetence? Zee you, Michael gutmann@uni-duesseldorf.de
