Hi,

I'm writing something generic in a python script which has to test if an object is an objectmanager or not, since I want it to work with Folders but also with user defined types which inherit from objectmanager.

How can I do that ?

thanks.

Folderish objects (based on ObhectManager) have an attribute, isPrincipiaFolderish. Just test for this property as in: if getattr(ob, 'isPrincipiaFolderish', 0): or <dtml-if name="isPrincipiaFolderish"> hth -- | Casey Duncan | Kaivo, Inc. | cduncan@kaivo.com `------------------>
