Zopemisters, Not sure if this is a bug. Is anyone else experienceing this: I add a ZClass. Then add a propertysheet called "Basic" (Using the default as much as possible:) Then when I call propertysheets.Basic.manage_editProperties, I get the AttributeError on "Basic". I searched the Collector and didn't see anything like it exaclty. Bug? All my best, Jason Spisak webmaster@mtear.com
