symfony2/doctrine entity property not filled - php

Question

After doctrine createQueryBuilder execute, I get results with a property of objects that is not filled.
here my code
In UserSecurityManager (service)
... $repository = $this->em->getRepository('VenusUserBundle:Role');
$query = $repository->createQueryBuilder('r')
->where('r.lft >= :role_lft AND r.rgt <= :role_rgt')
->orderBy('r.rgt', 'ASC')
->setParameter('role_lft', $result['lft'])
->setParameter('role_rgt', $result['rgt'])
->getQuery();
$availableRoles = $query->getResult(); ...
//debug
foreach ($availableRoles as $key => $value) { echo '<br>CODE='.$value->getCode().' LFT='.$value->getLft().' NAME=('.$value->getName().') * '; }
...

The line
foreach ($availableRoles as $key => $value) {
echo '<br>CODE='.$value->getCode().' LFT='.$value->getLft().' NAME=('.$value->getName().') * '; }
Display
CODE=client LFT=4 NAME=(client) *
CODE=studio LFT=6 NAME=(studio) *
CODE=commercial LFT=8 NAME=(commercial) *
CODE=user_manager LFT=11 NAME=(user manager) *
CODE=company_manager LFT=13 NAME=(company manager) *
CODE=admin LFT=3 NAME=(administrator) *
CODE=prod LFT=10 NAME=(prod) *
CODE=superadmin LFT= NAME=() * //<-- THE BUG : name is empty !!!
CODE=root LFT=1 NAME=(megaroot) *
And the data in database :
code parent_code name lft rgt
admin superadmin administrator 3 15
client admin client 4 5
commercial admin commercial 8 9
company_manager admin company manager 13 14
prod admin prod 10 15
root NULL megaroot 1 18
studio admin studio 6 7
superadmin root superadmin 2 15
user_manager admin user manager 11 12
for superadmin, The property "name" is not filled, I don't understand.
Do you have an idea ?
I made some other tests :
If the parent of role "administrator" is the role "client"
code parent_code name lft rgt
admin client administrator 3 15
client admin client 4 5
commercial admin commercial 8 9
company_manager admin company manager 13 14
prod admin prod 10 15
root NULL megaroot 1 18
studio admin studio 6 7
superadmin root superadmin 2 15
user_manager admin user manager 11 12
CODE=client LFT= NAME=() * <-- BUG HERE !!!
CODE=studio LFT=6 NAME=(studio) *
CODE=commercial LFT=8 NAME=(commercial) *
CODE=user_manager LFT=11 NAME=(user manager) *
CODE=company_manager LFT=13 NAME=(company manager) *
CODE=admin LFT=3 NAME=(administrator) *
CODE=prod LFT=10 NAME=(prod) *
CODE=superadmin LFT=2 NAME=(superadmin) *
CODE=root LFT=1 NAME=(megaroot) *
If the parent of role "administrator" is the role "client" and the parent of role "client" is the role "root"
code parent_code name lft rgt
admin client administrator 3 15
client admin client 4 5
commercial admin commercial 8 9
company_manager admin company manager 13 14
prod admin prod 10 15
root NULL megaroot 1 18
studio admin studio 6 7
superadmin root superadmin 2 15
user_manager admin user manager 11 12
CODE=client LFT= NAME=() * <-- BUG HERE !!!
CODE=studio LFT=6 NAME=(studio) *
CODE=commercial LFT=8 NAME=(commercial) *
CODE=user_manager LFT=11 NAME=(user manager) *
CODE=company_manager LFT=13 NAME=(company manager) *
CODE=admin LFT=3 NAME=(administrator) *
CODE=prod LFT=10 NAME=(prod) *
CODE=superadmin LFT=2 NAME=(superadmin) *
CODE=root LFT= NAME=() * <-- BUG HERE !!!
Thanks and sorry for my english.

Answer 1

If I execute
$query->setHint(\Doctrine\ORM\Query::HINT_REFRESH, true);
before
$availableRoles = $query->getResult();
ok, the result is good but I don't know the cause yet :s.
The problem come from my code ?! or it's a bug in doctrine 2.4 ?

Answer 2

it would be a problem with doctrine cache.
When I call this "entitymanager->clear()" before execute query, all is good.
$this->em->clear('MyApp\UserBundle\Entity\Role');
$repository = $this->em->getRepository('MyAppUserBundle:Role');
What's the explain of this problem of cache ? Because I don't configure caching in my symfony project.
is "em->clear()" dangerous for the rest of application ?
