Zopsters, I have a ZClass instance that can be created inside another ZClass instance. Both have different propertysheets with one property name that is the same. When I call manage_changeProperties on the child 's property sheet, is doesn't change the child's property, it changes the parent! Parent_properties myProperty:tokens Child_properties myProperty:tokens When I call <dtml-call "propertysheets.Child_properties.manage_changeProperties( myProperty=REQUEST['myProperty'], )"> *Parent_properies* myProperty changes to REQUEST['myProperties'], not the one which was called. Can/Has anyone duplicate this? All my best, -- Jason Spisak webmaster@hiretechs.com
