True Stories of the XSD Editor

Sometimes when you're working, late at night, hunched over the BizTalk Schema Editor, things just don't seem to work right.

Case in point: right now.

I have a map with a section in the middle of it that looks something like:

While working with the project containing this schema definition I started running into errors. Specifically, <ContractId> was okay, but <CustPO> seemed to be suddenly invalid. Messages start blowing up coming into the system.

The fix for this:

1. open your offending schema definition with the editor.
2. delete all of the nodes inside the record
3. re-create all of the nodes you just deleted
4. validate - now it works!
5. redeploy 'new' schema definition and be on your merry way.

The schema in questoin does import a couple of definitions from a 'global' schema project, but <Project> isn't a part of any of those other than being part of the schema that uses the definitions...
