[TYPO3-mvc] Define a PID per object, not by configuration

[Adrien Crivelli]

Hello list,

I'v struggled for a few days with PID storage. I am at the point where I
need advice before doing some very ugly things.

I need to read and create objects on many several PIDs. For a while I manage
reading what I needed by extending Tx_Extbase_Persistence_Repository with:

abstract class My_AbstractRepository
{
 public function createQuery()
{
 $query = parent::createQuery();
$query->getQuerySettings()->setRespectStoragePage(FALSE);
 return $query;
 }
}

Now I need to create object and it is not as simple as that. According to
the latest documentation <http://forge.typo3.org/issues/3698#note-15> I
found, PID are set by configuration. In several ways, but always
configuration. That means PIDs are kind of static data. It doesn't fit my
needs as I usually want to store object on the current page (as my project
is a BE extension using ExtJs, "current page" isn't necessarily so
straightforward).

Of course I tried things like:
$newNewsletter->setPid(12345);
 $this->newsletterRepository->add($newNewsletter);

But, as many before me, it wasn't long before I figured out that the PID is
always overwritten by the configuration
(via Tx_Extbase_Persistence_Backend::determineStoragePageIdForNewRecord()).


So the first question is simple: Why can't we manually set a PID without
being overwritten ?

Cheers,
