Hi Tony, I changed the grid definition slightly from what is posted above, but the grid is still not being loaded with data. Rather than use xmlreader as the datatype, it is now using xmlstring because the xml comes over as part of the response rather than in a file.

The grid definition is followed by the text of the response below. I've verified that ccXml is being properly set with the xml in the response.

Thanks for any help you can provide.

I was able to resolve this by including colNames in my grid definition and providing empty quotes for the hidden columns.
