I tried to use the JSON Schema support last night, and it keeps telling me "Type is not allowed" whenever I have an 'array' type. I've tried an example from the json schema site, and I've run it through a web-based validator to make sure it wasn't something I was doing wrong.
Sample Data: http://json-schema.org/example1.html
I removed the warehouse information from the last sample on the page because I saw the bug report for non-relative references not working. The rest *should* work, though, but doesn't.
