one-to-many model validation

[Alberto Ruffo]

Hello, if i consider this tables:

Customer

-----------------------------

id, name, surname

AND

Address

-----------------------------

id, address, number, city, customer_id

Customer has more addresses, so:

$address = R::dispense...

$address->import(...); // for instance, from $_POST['address']

$customer = R::dispense...

$customer->import(...); // for instance, from $_POST['customer']

$customer->ownAddress[] = $address;

try {

R::store($customer);

} catch (ModelException $e) {}

In this case, how do model validations work? 

I have to throw exception once and retrieve errors of both at the same time; but there are two model-validations which need two exceptions.
