Subject Re: "/" character an invalid key?

My first guess would be that OGNL is trying to evaluate it, although
since it's a string, not sure that makes any sense.

I don't know how your DB is laid out or how what sounds like ad-hoc
structures are being created, but is a text ID really the only thing
you have available?
