symfony2/doctrine entity property not filled

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 ?
