[SOLVED] Doctrine2: OneToMany on mapped superclass

Doctrine2: OneToMany on mapped superclass

My DB structure is as follows:

work:

CTI table Work
MappedSuperclass table AbstractImageWork which extends Work
final table PhotoWork which extends AbstractImageWork

comment:

MappedSuperclass table Comment
final table WorkComment which extends Comment

WorkComment has a ManyToOne relation to Work:

@ManyToOne(targetEntity="Work", inversedBy="comments")

Work has a OneToMany relation to WorkComment:

@OneToMany(targetEntity="WorkComment", mappedBy="work")

The problem is that Doctrine gives me this error while updating the schema:

[Doctrine\ORM\Mapping\MappingException]
It is illegal to put an inverse side one-to-many or many-to-many association on
mapped superclass 'Acme\...\AbstractImageWork#comments'.

I guess this has something to do with the MappedSuperclass AbstractImageWork stuck in the middle between Work and PhotoWork, but I didn't actually put this relation on the MappedSuperclass, but on the CTI table.. so why will Doctrine behave like this?

Any ideas?

Solution

In some cases, when you have such error when inherit from the class that is tagged as @ORM\MappedSuperclass, try to change your properties access level from private to protected
