I'm aware it's not supported -- There's a nice feature in ORM for Hierarchical NestedSet support that seems really useful and clean.. I'd like to take advantage of it with Silex : Here's a link -- http://www.doctrine-project.org/projects/orm/1.2/docs/manual/hierarchical-data/en

I've also been looking at the Gedmo Doctrine Extensions but I'm not sure where to start integrating them into Silex as they seem to use ORM too.
