Yes, but what about putting a property in the bizobj, like ParentDeleteLogic, defaulting to None, which means to go with however the Parent's deleteChildLogic is set. And, what about propertyizing these attributes while we are at it? This way, I could do: """ self.bizShapeEffect = ShapeEffect(app.dbConnection, ParentDeleteLogic=kons.REFINTEG_IGNORE) self.addChild(self.BizShapeEffect) """ Paul _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/dabo-dev Searchable Archives: http://leafe.com/archives/search/dabo-dev This message: http://leafe.com/archives/byMID/[email protected]
