I will go back home and check the wiki pages. In the meantime, here is what
I use to save
[Transaction]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Golfer golfer) {
if (golfer.IsValid()) {
golferRepository.SaveOrUpdate(golfer);
TempData["message"] = "The golfer was successfully
created.";
return RedirectToAction("Index");
}
else {
MvcValidationAdapter.TransferValidationMessagesTo(ViewData.ModelState,
golfer.ValidationResults());
return View();
}
}
When I put it the thru the debugger, I see that golfer instance has correct
values (from the form) for FirstName, LastName, Email as well as
Address.Addr1, Address.City etc populated correctly.
BTW, SaveOrUpdate if fine and when the "Create" method ends (i.e. the
transaction is complete) then I get the exception. Obviously, because the
flush is thrwoing the exception.
I still suspect that "cascade" on ManyToOne needs to set to "all", I am not
sure how to do it.
Thanks
Ramana
