Problems with validating a BizTalk-mapfile in VS.NET
I just spend two hours trying to figure out why my very simple map wasn't valid when using Validate Map. It turned out that I had changed a field name in the source schema, which was in a different assembly and I hadn't compiled that assembly yet. After I compiled it, I could succesfully test my map.
The error message I got was “Exception Caught: The map contains a reference to a schema node that is not valid. Perhaps the schema has changed. Try reloading the map in the BizTalk Mapper. The XSD XPath of the node is: <XPath for new nodename>“
