You receive a run-time exception but not an error message if the Copy Processing Instructions (PIs) property is set for multipart transform maps in BizTalk Server 2004 (870610)

The information in this article applies to:

Microsoft BizTalk Server 2004 Enterprise Edition
Microsoft BizTalk Server 2004 Developer Edition
Microsoft BizTalk Server 2004 Partner Edition
Microsoft BizTalk Server 2004 Standard Edition

SYMPTOMS

In Microsoft BizTalk Server 2004, the XLANG engine may throw a run time exception that is similar to the following:

Error encountered while executing the transform Transform_encoding.Transform_UTF_8.
Error: Invalid input/output document into/from the transform. Does not have a single root node

Exception type: XTransformationFailureException
Source: Microsoft.XLANGs.Engine
Target Site: Void ApplyTransform(System.Type, System.Object[], System.Object[])
Help Link:
Additional error information:

You do not receive an error message in the compiler.

CAUSE

This problem may occur if you have a transform shape in your orchestration that is transforming from multiple messages to multiple-part messages (many to many) and if the source documents (messages) have the Processing Instructions (PI) property and the Copy Processing Instructions property is set on the map.

MORE INFORMATION

The Copy Processing Instructions (PIs) property copies instructions only from one message to another single message. You cannot copy PIs to or from all the parts in multipart mappings (one-to-many or many-to-one).

You do not receive an error message in the compiler under these conditions. Instead, the XLANG engine throws a run-time exception.
