Hi Marcel,
I am confused about the UI - how do I create a new Object? Was in
CAY-604 patch?

Hi folks,
I am getting a nasty exception on the server side when working with
ROP. It occurs in very specific circumstances: I create a new
object, save it back to the server. When I try and look at that
object again, I get the exception below.
My insert process is basically context.newObject, and then set the
relationship from the existing object to point to the new one.
The odd thing is that the SQL logs show that the DB query works
perfectly: the correct number of records are returned without a
problem. And even more strangely, if I restart the servlet it works
perfectly. Also, I think it is new since moving to 1.2 (90% sure).
Any ideas? I don't know where to start on this one.
Regards,
Marcel
