Jira issue originally created by user naderman:

Consider this example:
select g.id, u.id, u.status, count(p.phonenumber) numPhones from Group
* g join g.user u join u.phonenumbers p group by g.id, u.status, u.id

With data:

phonenumbers:
    [1, 2, 3, 4, 5, 6]
users:
    [{id: 1, status: developer, phonenumbers: [1, 2]},
     {id: 2, status: developer, phonenumbers: [3]},
     {id: 3, status: developer, phonenumbers: [4, 5, 6]}]
groups:
    [{id: 1, users: [1, 2]]},
     {id:2, users: [3]}]

The result currently is:

array(
    array(
        0 => object(CmsGroup) {
            'id' => 1,
            'users' => Collection(
                object(CmsUser) { 'id' => 1 },
                object(CmsUser) { 'id' => 2 }
            )
         },
        'numPhones' => 1
    ),
    array(
        0 => object(CmsGroup) {
            'id' => 2,
            'users' => Collection(
                object(CmsUser) { 'id' => 3 }
            )
        },
        'numPhones' => 3
    )
)

Note that the first entry contains only one value numPhones => 1, even though there are two users associated with that group. One of whom has 2 phone numbers and the other has 1.

The result I would expect is:

array(
    array(
        0 => object(CmsGroup) {
            'id' => 1,
            'users' => Collection(
                object(CmsUser) { 'id' => 1 },
                object(CmsUser) { 'id' => 2 }
            )
         },
        'numPhones' => array(2, 1)
    ),
    array(
        0 => object(CmsGroup) {
            'id' => 2,
            'users' => Collection(
                object(CmsUser) { 'id' => 3 }
            )
        },
        'numPhones' => array(3)
    )
)

The difference is that numPhones for each row now contains an array of the
scalar values matching the corresponding users.
