Newbie question =)

Hi all,

   Here's a situation I have, and I'm trying to figure out how best to do it 
using Modeling.

   I have a Person entity, and it has a ToMany relationship with BankAccount 
entities. One of the attributes of BankAccount is "isDefault", which is 1 if 
the particular account is (duh) the default one, and 0 otherwise.

   So part of the validation logic for validateIsDefault(), I figure, should 
make all other BankAccounts' isDefaults set to 0 if this new account is set 
to 1.

   The problem is that I'd like to get at the editing context which is 
calling validateIsDefault in the first place, so that changing the other 
isDefaults to 0 would *only* happen if the entire new account gets correctly 
saved. (In other words, the ec I create in this function, I think, should be 
a nested ec of the calling ec.)

   Is there a way to do this? Or am I going about this in the wrong way?

   Thanks for any insight!

~Tom
