Im not sure if you have check out Struts Shale, a subproject that is built on JSF. http://struts.apache.org/shale/index.html One of the key features is this notion of a view controller that adds additional life cycle hooks in a specialized managed bean. The view controller assumes a relationship to a JSF view id. Shale fires these life cycle events without method bindings in your page. I expect that's why it's called a view controller verses a view model. http://struts.apache.org/shale/features.html#view This pattern promotes the ViewController as the handler of action event callbacks. From the view controller you have access to other managed beans so there is not a limitation. I like the separation we see in struts between the data and data handler. You can easily do this by mapping your value binding expressions to an aggregated object on the view controller that is created as a managed bean (kind of like using multiple form beans from a struts action).
