FIX: The BizTalk Server 2004 Business Rule Engine may use incorrect values when it evaluates a rule

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was corrected in BizTalk Server 2004 Service Pack 1.

The BizTalk Server Business Rule Engine improves performance when you handle XML documents by caching the value that is retrieved. Therefore, the value does not have to be extracted from the document every time that it is used. Sometimes, the engine incorrectly uses the value that is cached from a different node.
