child object and updated id upon insert and expected result

Hi everyone,

I'm not clear on the following expected behaviour.
RootObjectList--->child object
items--->item

I do the following for a new item
Items items = Items.NewItems();
Item item = Item.NewItem();
/*  populate some properties etc.  */

items.Add(item);
// at this point item.ItemId has a value of zero, which is what I expect

items.Save(); 
// items gets saved, in item object insert there is the following code
// itemId = (int)cm.Parameters["@NewitemId"].Value;
// which works correctly, if I put a break point here, I will see itemId have the correct value
// that matches the database value

int temp = item.ItemId;
// at this point I expect temp to have the database value.
// but it does not it is still zero.


My question is: is the zero expected behavior or have I gummed something up and the value should be the new value?

Thanks in advance
harry

The answer is almost always this one:

When you saved the BO you just called .Save on it like this:

MyBO.Save

What you need to do to see the returned value is this:

MyBO = MyBo.Save

You have to update your reference in the UI.
