Symfony2: spl_object_hash() expects parameter 1 to be object, string given in Doctrine
I have finally found the problem:
When creating the object user, instead of setting those fields
$user->setDegree();$user->setWorkplace(); $user->setJobtype();$user->setResearchField();as objects (because of the OneToMany relation), I gived here only a string, from the form.
So, for those fields, the code would be:
$degree = $em->getRepository('SciForumVersion2Bundle:Degree')->findOneById($enquiry->getDegree());$workplace = $em->getRepository('SciForumVersion2Bundle:Workplace')->findOneById($enquiry->getWorkplace());$job_type = $em->getRepository('SciForumVersion2Bundle:JobType')->findOneById($enquiry->getJobtype());$research_field = $em->getRepository('SciForumVersion2Bundle:ResearchField')->findOneById($enquiry->getResearchField());And then:
$user->setPerson($person);$user->setWorkplace($workplace); $user->setJobtype($job_type);$user->setResearchField($research_field);So: Be careful when you are getting this kind of warnings, you probably have to check if you are populating your object in the right way.
