Doctrine 2 proxy classes breaking Symfony2 ACL
When attempting to run findAcl() on an entity with an existing entry in the acl_classes table generated by init:acl I get an AclNotFoundException.
Testing with createAcl() on the object in question before calling findAcl() shows a new record in acl_classes for a proxy class of the same type and the operation completes successfully.
This seems wrong, proxies should be transparent right, or am I missing something?
I'm am just answering this because i had a hard time to find a solution and this was the first result in google for me.
Yes, it's wrong and it's a known bug for symfony2.
Jonathan Ingram solved this, and wrote a post about it a while ago: http://jonathaningram.com.au/2012/01/13/overriding-the-objectidentityretrievalstrategy-to-check-if-a-domain-object-is-a-doctrine-proxy/
He created his own object identity retrieval strategy to override the default, and registered it in the services.xml (see the post above). Actually it's a pretty simple and straightforward solution, i am a bit ashamed i didn't figured it out on my own :)
In symfony2.1 it's not a problem any more, see: https://github.com/symfony/symfony/pull/3826
