DataRelation problem that doesn't make sense

[sklett]

I've set up a datarelation and am getting the oh-so-popular "These columns
don't currently have unique values"

looking at it, I don't see the problem
parent column values:
1
2
3
1
2
3

child column values
1
1
1
2
2
2
3
3
3

This worked fine when the parent column only had:
1
2
3


but as soon as I added an additional 1,2,3 I get this exception. Now
datarelations work on a per row basis, right?
If that is the case, this seems to me as though it should work. I can't
think of another way to do this.

Hopefully someone can clue me in on this...

Thanks,
Steve!

You should not have repeted values in the set
