---------- As it is unless he understands the effect the group by clause can have (this is the same group by clause that Dr Kay said he was raising a specification bug about yesterday) he is going to be baffled as to why he is getting an error telling him he has duplicate attribute nodes because he doesn't think he's coded any.
Brought up to another level ... I think this is generally true. If a person does something that tells a system to do something very different than what the person thought was being asked, And especially if the "error" is far enough out of context then error messages can be very confusing. If the computer had enough context, and perhaps AI and ESP and could deduce "OH you thought you were doing THIS but you did THAT instead and I didn't like that" it could produce better messaging. It's a noble but tough problem ... Its hard enough for computers to reliably report on things that go wrong, To ask them to diagnose what you thought you were doing that caused it to go wrong is asking a lot. Someday maybe they will be able to do that. In the meantime us computer users have to struggle with a literally mindless machine as best we can. -David ---------------------------------------- David A.
