"Set Role and losing data"

tbagley85

So I have a data set which has an attribute (let's call it foo) as an id. And the values for each example are Strings - "a", "b", and so forth. I then pass that data through a Set Role "foo" to regular, and I lose most of the values of foo, but ONLY foo. So if a point went in ["foo":"c", "bar":"d", "cat":"dog"] it's coming out ["bar": "d", "cat":"dog", "foo":"?"]. Any thoughts?
