[FLOW3-general] Question to Bidirectional ManyToMany Relations with FLOW3 and CouchDB

[Thomas Kirst]

Dear all,

I'm trying to use CouchDB as Persistence Backend. But strangewise 
bidirectional ManyToMany relations seem to not work as expected.

In my example I have got 'Teams' and 'Employees'. A team has several 
members (=employees) and an employee is in one or more teams.

My models look like this:

[Model Employee]
class Employee {

   /**
    * Teams an employee is a member of
    * @var 
\Doctrine\Common\Collections\ArrayCollection<\IBM\IBMDB\Domain\Model\Team>
    * @ManyToMany(inversedBy="members")
    */
   protected $teams;
   ...
}

[Model Team]
class Team {

   /**
    * Team members
    * @var 
\Doctrine\Common\Collections\ArrayCollection<\IBM\IBMDB\Domain\Model\Employee>
    * @ManyToMany(mappedBy="teams")
    */
   protected $members;
   ...
}
---

When I now add one team to an employee it shows up in the database 
record (property 'teams').

---
"classname": "IBM\\IBMDB\\Domain\\Model\\Employee",
"properties": {
   ...
   "teams": {
      "multivalue": true,
      "value": [
        {
          "type": "IBM\\IBMDB\\Domain\\Model\\Team",
          "index": 0,
          "value": {
            "identifier": "1b31c104-c9e0-4c5a-980e-183d848d1f16"
          }
        }
      ],
      "type": "Doctrine\\Common\\Collections\\ArrayCollection"
   },
...


But on the other side the relation from the team to the employee is not met.

"classname": "IBM\\IBMDB\\Domain\\Model\\Team",
"properties": {
   ...
   "members": {
      "multivalue": true,
      "value": [
      ],
      "type": "Doctrine\\Common\\Collections\\ArrayCollection"
   },
...

As you can see the 'ArrayCollection' is empty and it seems like the 
'reverse way' does not work.

Is there anything I missed in the method annotations? With MySQL the 
bidirectional way works well.

Any ideas?

Thanks,
Thomas
