.setRows appears to be broken

Doesn't matter what XPATH I put in the .setRows call. The results don't change. I can put an XPATH like "//root/tom/dick/harry" and the grid will still show every row in the XML datatable, regardless of what the element names are.

Yes, it is broken if you call it after the data arrives (or after setXML call). In AW 1.0 and 2.0 it should be used before the data request.
