[Zope-dev] how to access propertiesheets of a base ZClass

in a derived ZClass I created a ZClass Field with a propersheet Basic with some Properties like: name,title,type,order and so on. I defined also a new view for this Basic Propertysheet FieldBasic. Now I defined an IntField ZClass with the Field as baseclass, and wanted to access and set for example the type-property. But in my new ZClass I don't have a FieldBasic management tab. If I create a new instance of Field I get the FieldBasic tab. any enlightment to this is welcome. Mit freundlichen Grüßen Joachim Schmitz AixtraWare, Ing.
