问题
it's an update form, if i try to update the first time it works but the second time i got this error:
Warning: filemtime(): stat failed for .../vendor/ocramius/proxy-manager/src/ProxyManager/GeneratorStrategy/EvaluatingGeneratorStrategy.php(54) : eval()'d code
and the exception is catched here:
$form->handleRequest($request);
What i understood that's liated to cache, so i cleared it. But i got always the same problem : it works just the first time after i got the same error
