symfony 2 - 一对一映射

Question

I am getting the following error, when I want to add new UserProfile using autogenerated form.The error is: Expected an object, but got a collection. Did you forget to pass "multiple=true" to an entity field?

I am using Symfony 2.0.12

This is my code for the UserProfile entity. The issue occurred in Controller, but I am not sure how to solve it. Please help.

The problem is in your form... Try this.

 public function buildForm(FormBuilder $builder, array $options) {


        $builder
->add('employeeType', 'entity', array(
                    'class' => 'MyProject\EntityBundle\Entity\Employee',
                    'property' => 'name',
                      'multiple'=>'true','query_builder' => function ($repository) { return $repository->createQueryBuilder('es')->orderBy('es.name', 'ASC'); },

}
