Re: [ptp-dev] Fw: Questions about JAXB parser

Dave,
I think I found the bug. There is a setValidator() method which is not being called anywhere. I'll see if I can't fix this now.

You would need a validator for that, as well as your alphanumeric examples. But for processor count, I would think a Spinner is good enough (that's what I put on the PBS mpi cores attribute).
