I recently changed JSF Spy to only work with JSF 2. It's a tough call though. I might be able to refactor such that we have a JSF 2.x version and a JSF 1.x version.
The rest of JSFUnit will probably always be compatible with JSF 1.1, 1.2, and 2.0.
No problem with the decision to move JSFSpy to JSF 2 only... Just wanted to give JSFUnit another trial run in our application and started with JSFSpy... so I got a bit nervous... (btw... I like the name JSFSpy)
