Symfony2 After form submit entity not extended on base entity - php

Question

In editAction method of controller I tried to edit existed entities in class table inheritance.
But after form submit I get error:
Neither the property "id" nor one of the methods
"addId()"/"removeId()", "setId()", "id()", "__set()" or "__call()"
exist and have public access in class "AdBundle\Entity\AdFlat".
Why AdFlat entity not extended of AdBase entity?
Base entity:

Answer 1

The error message simply states that you are missing a way to set the entity's $id property. It doesn't tell you anything about the class not extending the base class. However, your base class only defines a getter method for the $id property but no setter method.

Answer 2

Doctrine Entities work as POPOs (Plain Old PHP Objects). To achieve extending correctly you need to work with the MappedSuperClass here is an example
