Hello,

i got that following setup:

Page-Class width 2 $has_many relations, to: lets say "Customer"- and "CustomerPremium"- DataObjects.
My CustomerPremuim - Class is a direct Subclass of Customer.

Now i want an db-write - operation (update a Field) on each related CustomerPremium DataObject in that onAfterWrite() - Method on the Page-Class.

If i target the Parent-Class "Customer" with "$this->Customer()" the write() Method works, but not on the Subclass.
Even since the Subclass has its own $has_many relation in Page.

Any Idea why is that?

if i print out the result of the iteration i get my regular DataObjects in any case. So i'm wondering that i cant write to it just because
its an Subclass.

my code is:
class Page extends .... {

$has_many {
"Customers" => "Customer",
"CustomersPremium" => "CustomerPremium"
}

function onAfterWrite(){
      foreach($this->CustomerPremium() as $i) {
         $i->Format = "482 x 288";
         $i->write();
      }

      parent::onAfterWrite();

.....

Thanks!
