Hey there,
there doesn't really seem to be a clean way with Propel 1.2, but a
possible solution isn't too complex.

Something's wrong with your schema and the output you are looking for,
since each customer can have only one item assigned. Anyway, suppose
your schema looks like this:
item:
customer_id:
customer:
id:
you can build a criteria, fetch the rows and then manually loop through
the resultset adding the items to the customers as you go. Something
like this:
$c = new Criteria();
$c->addJoin(CustomerPeer::ID, ItemPeer::CUSTOMER_ID);
$rs = CustomerPeer::doSelectRs($c);
$customers = array();
while ($rs->next())
{
$customer = new Customer();
$id = $rs->getInt(1)
if (!isset($customers[$id]))
{
$customer->hydrate($rs);
$customers[$id] = $customer;
}
$item = new Item();
$item->hydrate($rs, CustomerPeer::NUM_COLUMNS);
$customers[$id]->addItem($item);
}

Should work quite similar to the 1:n case with a slightly different JOIN
condition.
