Article ID: 894177

APPLIES TO

Microsoft BizTalk Server 2004 Service Pack 1

SYMPTOMS

When you use the Transform shape in a Microsoft BizTalk Server Orchestration to generate a map file after you have installed BizTalk Server 2004 Service Pack 1 (SP1), you may receive the following error message when you try to validate the map:

Exception Caught: Cannot use a prefix with an empty namespace.

Note This problem does not occur in BizTalk Server 2004 without SP1 installed.

CAUSE

This problem occurs when you provide multiple source inputs for the map and the source schemas do not have a Target Namespace property specified. Therefore, the generated map will contain a namespace attribute that is null. When the Target Namespace property is not specified, the map generation process should not put the namespace attribute in the map.

Apply this hotfix only to systems that are experiencing this specific problem. This hotfix might receive additional testing.

MORE INFORMATION

Steps to reproduce the behavior

In Microsoft Visual Studio .NET, create a new BizTalk Server project.
Create a new schema, and then set the Target Namespace property to nothing.
Create a new BizTalk Server Orchestration, and then create three new message types.
Set the Identifier property for the three message types to the following values:
- Source1
- Source2
- Destination1
For each message type that you created in step 3, set the Message Type property to the schema that you created in step 2.
Add a Transform shape to the orchestration.
Right-click the Transform shape that you added, and then click Configure Transform Shape.
In the Transform configuration dialog box, set two Source messages to Source1 and Source2, set one Destination message to Destination1, and then click OK.
In Solution Explorer, right-click the map that you generated in step 8, and then click Validate Map.
