Hi there,
I've done a search regarding this error message on your site but I'm spinning my wheels trying to understand it. Error Message: Requested unknown parameter 'LASTNAME' from the data source for row 0. I get this when I click on the EDIT button and after making a small change on one of the fields, regardless of which one, and click on the UPDATE button. A request is sent to the server and it returns a valid JSON string. I'm hoping you can point out the error of my ways. Please advise.
