OK, here is the problem:
I currently have this:
rtvHeader : RtvHeader( status != StatusConstants.MATCHED | !=
StatusConstants.APPROVAL )
but if I switch it to use a quoted string value like the following:
rtvHeader : RtvHeader( status == "Matched" | == "Approval" )
It works...Is this a bug?

As another note, the JBoss Rules IDE is NOT reporting any errors with the
syntax.
