Message:

On PHP >=5.4, use proper way for instantiating classes without invoking constructor.

Consider this code:

$dql = "
    SELECT Page, Product.name
    FROM Dlayer\\Entity\\Page Page
    INNER JOIN Page.Product Product
    ";
$q = ($em->createQuery($dql));
foreach ($q->iterate() as $entry) {
  $page = $entry[0][0];
  $name = $entry[0]['name'];
}

This results with undefined index: 'name' for the second entry.

First result keys are (notice just one array element with index 0):

0
array(2) {
  [0] =>
  int(0)
  [1] =>
  string(4) "name"
} 

but all others are different (notice two array elements with index 0 and the other one that is incrementing):

the second one:
0
array(1) {
  [0] =>
  int(0)
}
1
array(1) {
  [0] =>
  string(4) "name"
} 
the third one:
0
array(1) {
  [0] =>
  int(0)
}
2
array(1) {
  [0] =>
  string(4) "name"
} 

What's wrong with this approach? Is it a bug or mixed results should not be used with the iterate method?

As I sayd in the title, it would be nice if the ORM layer could permit to map a 1:n association in the db as an unidirectional OneToMany in the classes, without using a JoinTable in the database.
This would permit us to get rid of the unnecessary database JoinTable, which creates disorder and decreases performance for no valuable reason.

Is it possible?
