Connect SOAP MTOM enabled fails Pega 7.2.2 version of HFix-28742



After upgrading to Pega 7.2.2 from Pega 7.2.1 Connect SOAP request messages are failing on back end server with the error "xop 3.2.2.a: xop:Include must be the sole child of element"

Examining the SOAP message sent from Pega server, it might be that the base64binary is not being substituted correctly with the expected "XOP Include" element.

Error Messages

Steps to Reproduce

Not Applicable

Root Cause

While validating an MTOM/XOP optimized message, an xop:Include element was encountered in a simple type context, inside an element with other children element.

The xop:Include element may only be used to replace base64 encoded content that is the sole child of its parent element, and must completely replace that content.

Therefore, no text, comments, processing instructions, or other elements are allowed surrounding the xop:Include element.


Apply HFix-33171.
