[Zope] External Method

[Tom Deprez]

Hi,

Yes, this gives me parents, but it doesn't work for my problem :

The external method is used for storing the information into a ZCatalog.
Now, when the Catalog is updated, I get the wrong parents, I get the
parents of the catalog and not of the object itself. :-(

Somebody another idea?

Tom.
