I've been able to get it working by modifying the flags in the wire protocol handling. There is a version of MongoTalk I do use here: http://smalltalkhub.com/#!/~philippeback/HOExtras/packages/ConfigurationOfMo... This is drifting a bit from the official one and maybe I should integrate things back. What I have in it is some extra doc comments... I think that it is important to beef up the support for MongoTalk as we are severely lacking on that area vs other platforms. This includes: * support for replicasets (this is handled in client code) * support for GridFS (nothing in MongoTalk) GridFS shouldn't be too hard but replicatsets is another matter. I guess I'll learn a bit. Phil -- View this message in context: http://forum.world.st/MongoTalk-UpdateOperation-and-options-How-to-tp4827731...
