VERIFIED SOLUTION i

Resolve the ActiveX control not always sending the data to the server

Product Feature: ActiveX Editor

Operating System: Windows 2008
 
Within the XSD you must ensure that you supply the correct response, so if you have the XSD enumeration at this line only allows 'y' and 'n', sending a 'N' will fail.

This problem relates to a new data source and the "old" ActiveX control not reporting XSD validation errors.

So validate the XML to ensure that cases are correct and the data sent fits what is expected.
