Yeah, me too – I don’t get why it works that way. I didn’t try without the ViewFields, if I remember rightly.

I meant to try (and never did) a list with multiple multi-select columns. I wondered if combinatorial explosion was a possible issue.

But nope, that was the last I found out about it. One of those “Weird, but I have to get it working” type of problems.

I know that this is an old post, but I just ran across it while researching the exact same behavior as I’m working on SPServices.

In my testing, I find that if I *don’t* specify the ViewFields, I don’t get the duplicate items. I think it’ll probably solve things for me, but I’m still puzzled by why this works the way it does.

I’d appreciate it if you could let me know if you ever found out more…
