Hi, I've a question about "z3c.zalchemy" : "alchemy:engine" directive make for register a new AlchemyEngineUtility. It's possible to set a name to utility. However, z3c.zalchemy.datamanager.getSession can't catch named AlchemyEngineUtility ! It's a feature or a mistake ? one forget ? Thereof z3c.zalchemy.demo.demo1 can't work ! Regards, Stephane
