As of tonight, I have Trinidad up and running against JSF 1.2 with (nearly) fully JSF 1.2-ized APIs - running against the new EL, proper generics, (some) invokeOnComponent() support. There's still a few smaller tasks left, but anyone looking to run Trinidad on a JSF 1.2 server can build the code from:
