myEO.snapshotDictionary().hashCode() ? That would be based on the attributes values only. hmmm ... not sure how it would deal with relationship though (with regards to faulting). > I could use a "last modified" date and generate a MD5 of that too, but that > date is a better option for the Last-Modified header. jfv _______________________________________________ Do not post admin requests to the list.
