DDC-3193: Paginator hydrating the iterator with only half the limit #3976

Jira issue originally created by user alanhartless:

When using paginator on a left join for a one to many association, Doctrine is only hydrating half the requested results via the limit set by setMaxResults(). It is giving the correct total as indicated by count() but getIterator() is only returning half the requested results.

For example, I have 82 results, with a setMaxResults(50), getIterator() only has 25 hydrated!

My entities are:

* @ORM\OneToMany(targetEntity="Result", mappedBy="submission", cascade={"persist", "remove", "refresh", "detach"})
private $results;


 * @ORM\ManyToOne(targetEntity="Submission", inversedBy="results")
 * @ORM\JoinColumn(name="submission_id", referencedColumnName="id", nullable=false, onDelete="CASCADE")
private $submission;

And I'm using the following query builder in the submission repository:
$q = $this->createQueryBuilder('s')
->select('s, r')
->leftJoin('s.results', 'r')

It seems to be counting each submissions result as one rather than each submission. So it is returning 50, although its 50 results within 25 submissions. I need to find a way to get it to return 50 submissions instead. Maybe I'm doing something wrong?

Can you post your code configuring the paginator too ?

Looks like this was my bad. After getting frustrated with trying to get it to work, I had tried all kinds of things including $results = new Paginator($query, false); while I was debugging to see if $fetchJoinCollection made a difference. I had rearranged my query multiple times but forgot to remove the false so of course it continued to fail. Now that I've removed it (so it defaults to true), the query works correctly.
