Hi all,

After updating today Doctrine 2 from master branch I'm getting:

Entity of type "Entity" is missing an assigned ID. The identifier generation strategy for this entity requires the ID field to be populated before EntityManager#persist() is called. If you want automatically generated identifiers instead you need to adjust the metadata mapping accordingly.

Was there a change on the mapping of ID generation strategy? I was using a commit of the master branch from 1 o 2 weeks ago and it was working ok. I took a look at the repo for changes on the last days but I couldn't find anything related to this.

I paste the mapping and entities here:

Element:

/****
 * @ORM\MappedSuperclass
 */
abstract class Element
{
    /****
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    protected $id;
}

File:

/****
 * @ORM\Entity
 * @ORM\Table(name="file")
 * @ORM\InheritanceType("JOINED")
 * @ORM\DiscriminatorColumn(name="discriminator", type="string")
 * @ORM\DiscriminatorMap({
        "image"  = "Image",
    })
 */
abstract class File extends Element
{
     // Fields
}

And Image:

/****
 * @ORM\Entity
 * @ORM\Table(name="image")
 */
class Image extends File
{
     // Fields
}

Thanks in advance!

Do you "use" the mapping AS ORM namespace?

Yes, sorry for not including that. I had to add this to my entities 1 o 2 weeks ago when I updated all my vendors:

use Doctrine\ORM\Mapping as ORM;

Is it still right?

Great!

I want to say just in case BTW that removing the mapped superclass and moving all its fields to, for example, "File" makes the error go away.

Thanks a lot!
