Foreign keys as part of primary key are not supported currently.
Many thanks -- I had got that impression from other posts, I just need to see it in black and white.
Is there a list of supported and unsupported features anywhere?
Not sure about the list as it is, but consider a Start Guide at sf.net and Dain's paid docs.
No there is no list, but if you want to write one, that would be very cool.
You say you can create composite primary keys with a mix of both Foreign Key and normal fields.
I'd like to do that. I was thinking it was impossible.
Do you have an example or references to look at for this ?
