Get PersistentCollection::getDeleteDiff is empty when collection changes from 1 item to zero items

Bug Minor Awaiting Feedback Unresolved All Benjamin Eberlei Lee Tue, 31 Jan 2012 18:38:16 +0000 Sat, 9 Feb 2013 21:52:48 +0000 ORM 2 1 Same problem here. I wanted to write some unit tests, checking the entity relations and ran into exactly the same problem. Maybe my code can provide some more information (Group entity is the owning side, role entity is the inverse side): WHAT DOES NOT WORK: <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> /** * Test ArrayCollection */ $group = new Group('Group Test'); $em->persist($group); $em->flush(); $groups = new ArrayCollection(); $groups->add($group); $this->role->setGroups($groups); $this->assertEquals($groups, $this->role->getGroups()); /** * Test PersistentCollection */ $em->persist($this->role); $em->flush(); $groups = $this->role->getGroups(); $groups->removeElement($group); // first remove element before adding a new one $group = new Group('Group Test 2'); $em->persist($group); $em->flush(); $groups->add($group); $this->role->setGroups($groups); $this->assertEquals($groups, $this->role->getGroups()); </pre> </div></div> WHAT WORKS: <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> /** * Test ArrayCollection */ $group = new Group('Group Test'); $em->persist($group); $em->flush(); $groups = new ArrayCollection(); $groups->add($group); $this->role->setGroups($groups); $this->assertEquals($groups, $this->role->getGroups()); /** * Test PersistentCollection */ $em->persist($this->role); $em->flush(); $groups = $this->role->getGroups(); $group2 = new Group('Group Test 2'); $em->persist($group2); $em->flush(); $groups->add($group2); // first adding a new element before removing one $groups->removeElement($group); $this->role->setGroups($groups); $this->assertEquals($groups, $this->role->getGroups()); </pre> </div></div> Hope this helps in any way... I tried figuring it out on my own but I am too drunk right now xD Thanks for the report, formatted it Which version is that btw? Occurs in version 2.1.6 If group is the owning side, why do you only set Role::$groups? This has to be the other way around or not? @Steve I cannot reproduce your issue. Attached is a test script. Your code is very weird btw, why are you getting and setting groups collection? It is passed by reference so you can just have something like $role->addGroup() and $role->removeGroup() and encapsulate the logic? Also your tests are pretty useless, you check if two variables which are the same reference to the same collection are the same. Which should always be true. @Lee Can you provide more details? I cant verify this without more details. Can anyone provide us with more feedback?
