hi Keith,
now am i unable to use GeneralizedFieldHandler for generic issues
(e.g. manipulating all boolean values). As i understand from your
mail, it's supposed to add custom references to binding file for each
generated object and each field. isnt there any other generic solution
similar to FieldHandlerFactory?
It would also be appriciated to get an example if possible.
thanks a lot
mesut
