dWhen executing this code:

$this->items = $object->getItens();
...
foreach($this->items as $item)
{
...yadda yadda $item->getId() yadda yadada
}

within a symfony action, the php engine throws:

Notice: Indirect modification of overloaded property  xxxActions::$items has no effect in xxxactions.class.php

That’s related to a php bug , whose implications in symfony are described here. It looks like it’s related to php 5.2. I can see it appears on version 5.2.0  . It looks like the bug is gone in version 5.2.4.

Anyway, the simple workaround: insted of iterate through $this->items, we do:

$items = $object->getItems();
...
foreach($items as $item)
{
...yadda yadda $item->getId() yadda yadda
}
$this->items = $items;


and that’s it.
