It's the first that i use the Sonata Admin Bundle. It's looks like pretty cool. But if somebody can explain to me something particular with the differents roles and the display.
With a role : ROLE_SUPER_ADMIN It's display only my entities but not the sidebar.
With a role : ROLE_SONATA_ADMIN It's display in the sidebar but not my entites.
It's could be very great to merge the both. Thank you for your advices and your help.
