If write this configuration:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> $connection['driver'] = 'pdo_mysql'; $connection['user'] = 'root'; $connection['password'] = 'mypassword'; </pre> </div></div> <p>everything works.</p> <p>Weird... Just went through the code and everything looks fine (See `Doctrine\DBAL\DriverManager#getConnection()`)</p> <p>Can you check the spl_object_hash of your PDO instance and the one in the DBAL driver? What's your `Connection#getDriver()`?</p> <p>I checked the code again and I discovered, that happens If you use Doctrine\ORM\Query\Exec\SingleSelectExecutor with cache but is still a bug. Sorry to confuse you.</p> <p><a href="http://www.doctrine-project.org/jira/secure/ViewProfile.jspa?name=mdobak" class="user-hover" rel="mdobak">Michał Dobaczewski</a> can you provide the code to reproduce this then?</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> &lt;?php use Doctrine\ORM\Tools\Setup; use Doctrine\ORM\EntityManager; require __DIR__ .
