问题
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?

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
