To me, the error appeared like this: "-9966: The data returned by FileMaker Server Advanced was not in proper XML format."

I discover the problem as being the need of a portal in a related field. If you have related fields in a Layout, just put a portal to contain them, and the problem might be solved.

Somehow, a Control-Z (EOF) character snuck into the middle of a FileMaker text value that was being converted to XML by the Web Publishing Engine in FileMaker Server 13.0v3. This triggered Lasso 8.5.6 to report error -9966 (Could not understand the FileMaker Server Advanced response) when trying to load the record.
