I'm testing Prometheus and I think it's an interesting module/approach for those, like me, who have a Java enterprise background with MVC frameworks. So developement with Drupal can be more natural.
I followed the first steps of the tutorial (here: https://drupal.org/node/1408406), and I faced a little problem. I can't succeeded to render in a specific region (it renders the whole page), even when I these settings:
'template' => array(
'load_as_region' => 'content' // only load content to content area
I asked me if it's not related to a bug corrected in a previous module version, but that not be present in the latest module.
Anyway, I hope Prometheus will drag more interest from the community.
