Alexander, I just recieved the digest of the list, and I posted a similar question about how to use a counter property in Zope 2. The old way doesn't seem to be working. <!--# call "PARENTS[-1].manage_changeProperties(counter=counter+1)"--> doesn't add to the counter for objects below 2 down from the root folder. Funny thing is, it used to. Is this what you use for Globally unique id's? Jason Spisak webmaster@mtear.com
