Hi all, I created my first ZClass: ok Now I'd like to create a method for editing my class instances' properties, just for not using propertysheets/MyProperties/manage which is not the nicest to see. Ok, I created a DTML method with the front-end which calls a Script (Python) which should actually update the properties' values. I tried two ways of writing such a script: 1. context._updateProperty(name_property, value_from_form) It gives me an "IOError" while saving script changes (I suppose because it is an internal python method, it would works only if external, am I right?) 2. context.name_property=value_from_form It gives me an "Error Type: TypeError - Error Value: attribute-less object (assign or del)" when executed Now, probably it is a stupid Python question.. could you help me anyway? (I'd prefer to stay with just internal ppython methods) Thanks a lot Michele
