any 1 has clue how solve it?

thanks!

the sylius/rbac uses tree behaviour atlantic18/doctrineextensions.

you can use in symfony system using stof/stofdoctrineextensionsbundle.

once has been installed need enable tree behaviour in app/config/config.yml like..

stof_doctrine_extensions:     orm:         default:             tree: true 

this should make listener register correctly , fields auto-populated.
