Hi! I need a field in zope object which act as a sequence. I mean every time I create an object, the value is the previous sequence value of the last object created + 1. also I need to browse the objects by sequence (from the object 1 to the last, by the sequence number) I think I need a catalog FieldIndex to store the sequence for searches, a property in the object. Can I use the catalog to retrieve the max value of the index, so when I create the object, I just add 1 and store it in the property? TIA
