Problem	A response document containing a Fault element was received by the SOAPGenerator, but the GetFirstOccurence function for the Fault element returns 0.
Answer	The reason for the problem is that the XPath expression for the GetFirstOccurrence function searches for Envelope/Body/Fault. However, this is done on the document extracted from the Body element, and the extracted document has Fault as the top element. The above XPath expression does not correspond to anything in the extracted document and 0 is returned by the GetFirstOccurrence function.
Workaround	To fix this change the mapping on the 2 function calls found in the post point 'After handle Response' in the SoapGenerator function. Mapping in call to ...Fault.GetFirstOccurrence: `ObjectStoreReference -> Response<ObjectStoreReference>` `ObjectDocument -> Response<SOAPDocument>` `ParentElement -> <ParentElement.NULL>` Mapping in call to ...Fault.SingleFetch: ObjectStoreReference -> Response<ObjectStoreReference> ObjectElement -> unchanged (output from GetFirstOccurrence)
