Hi Brett,

your mapping of the n:m relation looks okay to me. I use similar
relations in my applications without problems. The only difference that
may have an impact is, that you set required="true" on the mapping of
the relation. Have you ever tried to remove that attribute?

I've removed it and gotten the same results; it was only in there because I was trying (once I had all these problems) to emulate the included JDO examples.

Yeah, it looks okay to me, too, except it doesn't work :-(

Thanks
