After i added a OneToMany Association to my Entity , the magic finder and any means to get results from database has stopped and i get A FATAL ERROR.

where i try to get a Slaplans Entity using the following code i get a fatal error:

$default=$this->_em->getRepository('ZC\Entity\Slaplans')->findOneBySlaplanid($planid);

I tried the queryBuilder but i get an error also when i run the getResult function.

Please help me .

For the holidaylinks variable(Slaplans Entity):

/**
     *
     * @param \Doctrine\Common\Collections\Collection 
     *
     * @OneToMany(targetEntity="Slaholidaylinks",mappedBy="planid", cascade={"persist"})
     */
    private $holidaylinks;

For the planid variable( Slaholidaylinks Entity ):

/**
     *
     * @var Slaplans
     * @ManyToOne(targetEntity="Slaplans",inversedBy="holidaylinks")
     * @JoinColumns({
     *  @JoinColumn(name="slaplanid", referencedColumnName="slaplanid")
     * })
     */
    private $planid;

This is how i fixed my problem :)
