Testing Schemas

I'm still having problems with the creating new schemas. In order to test, I've set the "Import" button to recreate a Schema object from the library and add it manually. I found that a created Schema with a Response but no States executes correctly, leading me to believe that the problem is in the State object.

However, a Schema with Response and both states fails to execute. In the first instance, State 1 had a null value for activeStates, State 2 was "full". A second Schema with Response and both States "full" also failed to execute.

I'm putting all my effort into creating Schemas at the moment. Creating and parsing XML is relatively easy, but useless if the Schema objects created from it won't execute. The next thing I'm going to try is editing existing Schemas. If I can change objects that already exist and work, it might shed some light on why creating schema objects from scratch doesn't.
