I try to create criteria groups to represent a hierachical organization. Each groups should have as members the users belonging to this group plus all the child groups. Basically is would like to create a criteria like members of this group with groupid=ID are - users having organization = ID - groups having parentOrganization = ID Is it possible to construct such a filter?

try this filter: /Person[Organization='ID'] | /Groups[parentOrganization='ID'] The magic is in the pipe | which acts like a Union in SQL saying get that set plus another.David Lundell www.ilmBestPractices.com
