Hey Dániel, @ealonso, @izaera,

This the display context changes that fixes the staging. I've added some staging related code as well, to reuse some code, but I've also changed the LayoutsAdminDisplayContext as well. It's not beautiful as we have discussed, but it is working now.

Dániel please review it, and Eudaldo, Ivan please let me know if you have any questions or concerns.

Thanks,

Máté
