Jira issue originally created by user else:

Dear developers,

I have class defined like this:


/****
 * @Entity
 * @HasLifecycleCallbacks
 */
class Shop*Data_Entity_Customer extends Shop_Data_Entity*Guest {
    /****
     * @OneToOne(targetEntity="Shop*Data_Entity*Contact", cascade={"remove"})
     * @JoinColumn(name="contact", referencedColumnName="id")
     */
    protected $contact;

}

when i run this:

$q = $em->createQuery("select c from Shop*Data_Entity*Customer c");
$q->setMaxResults(1);
$customers = $q->getResult();
$em->remove($customers[0]);
$em->flush();

I get "A detached entity can not be removed".

I don't understand it very well. I need to remove associated entity but it's not done and exception occurs.

I tried it with (like OneToMany)

/****
     * @ManyToMany(targetEntity="Shop*Data_Entity*Contact", cascade={"persist","remove"} )
     * @JoinTable(name="Shop*Data_Entity_Customer_*homes",
     *      joinColumns={@JoinColumn(name="customer_id", referencedColumnName="id", onDelete="cascade" )},
     *      inverseJoinColumns={@JoinColumn(name="contact_id", referencedColumnName="id", onDelete="cascade" )}
     *      )
     */
public $homes;

and

$q = $em->createQuery("select c from Shop*Data_Entity*Customer c");
$q->setMaxResults(1);
$customers = $q->getResult();
$em->remove($customers[0]->homes[0]);
$em->flush();

worked without problem like this.

orphanRemoval set it's not working so.

Thank for solve and perfect ORM!!! ;-)

Hi,

I created a test case (attached to this issue) that works well. Can you please modify that test so that it reflects your issue or tell me how to modify it so I can reproduce your problem? Thanks.

If you have the Doctrine tests checked out you can just copy this file into the tests/Doctrine/Tests/ORM/Functional/Ticket folder and run it with: "phpunit Doctrine/Tests/ORM/Functional/Ticket/DDC406Test".

Dear Roman,
Check this issue at first: http://www.doctrine-project.org/jira/browse/DDC-422 Maybe my extending cause also this issue. If you can't reproduce it with my extending write me and i'll try your test.

Thank you.

Andy

Dear Roman,
I can't understand how you could run that test.

First there wasn't set generatedValue strategy so i added it. It throw very stupid exception. Maybe it will be better to correct this error to understand what's wrong easier.

PHP Fatal error:  Undefined class constant 'Doctrine\ORM\Mapping\ClassMetadata::GENERATOR*TYPE*' in /home/else/download/doctrine/2.0.0-ALPHA4/lib/Doctrine/ORM/Mapping/Driver/AnnotationDriver.php on line 212

Then there wasn't set Column type so added either.

Then when i run test with "phpunit Doctrine/Tests/ORM/Functional/Ticket/DDC406Test.php" i got same error i reported.

I'm attaching edited test.

Andy

@GeneratedValue is the same as @GeneratedValue(strategy="AUTO"), AUTO is the default strategy, at least in trunk, and to run the test, you should check out trunk.

@Column is the same as @Column(type="string"), string is the default type.

It makes no sense to test against ALPHA4, please use trunk.

Your new test still works fine for me, again using trunk. So your problem might be already fixed.
