+++ This bug was initially created as a clone of Bug #1064526 +++ engine GUI (webadmin/userportal) is currently communicating with the engine-core (backend) via the legacy backend api; the GUI consumes this api via a GWT RPC servlet. We would like to: (1) stop GUI communication with the legacy backend api and start working with the "official" engine api (exposed via the rest api). (2) stop working with GWT RPC as our transport layer and simply work with direct requests to the engine's rest api (via an engine javascript SDK). more details here: http://www.ovirt.org/Features/Design/Using_REST_API_In_Web_UI
closing for now. will re-open if necessary.
