Seeing you are NEW to ColdFusion what I would do is pick ONE FRAMEWORK and stick to it. At first it will be hard you will have problems and you will be tempted to drop the Framework you have chosen but don’t do it. After you have mastered one framework then you can learn the others.
- CF Wheels
- ColdBox * * * (Nice Documentation)
- FarCry
- Framework/1 * * (simple LIGHT framework)
- FuseBox
- ModelGlue
- Mach-II
Most of these you can add
- ColdSpring
- Reactor
- Transfer
An introduction to ColdFusion frameworks at Adobe.com
Most important is to remember we all have our opinions but there is NO real proof what is best. You can even NOT use a actual framework and just code carefully in MVC.
The stuff you are currently maintaining
I would pick ColdBox, ModelGlue or Framework/1.
ColdBox provides a little Code Generation and Framework/1 is very light so less to learn.
