Hi,

Since Symfony Live 2015 and the @dunglas slides about ApiPlatform, I've read a lot on the future 2.7 serializer and wanted to give it a shot (MIT licence ftw).

I've replaced JMSSerializer by the Symfony serializer (v2.7). FIY I'm using FOSRest, FOSUser. Everything works as expected except for many-to-many relationships that leads to the circular reference error :

A circular reference has been detected (configured limit: 1).

It's easy to reproduce by using groups in a FOSUser class for example (gist of my use case).

I was wondering, is this an expected behavior or is it something that still needs a fix? Should I implement a repository that returns the result of the many-to-many relation or should the Serializer do the job by detecting the correct entity metadata?

Thanks!
