I've got a custom constituent tab that I'm getting an error with. My underlying local table has the column id_key per the instructions, and it's defined as int identity(1,1). On attempting to insert a column in that tab, I get an identity insert error. When I did a trace, it was indeed attempting to insert a (seemingly random) number into that column. Any ideas what would cause it to attempt that insert?
I don't think you want id_key to be an identity column, just an int.
