In other words, Faces Flow is a low-level API, whereas other frameworks, with BPM in particular, feature higher-level configurations and macro-level processes.

  • A JSF Faces Flow is modular in execution; a flow can invoke another flow in a nested fashion.

  • Faces Flow can pass parameters to another nested flow and the nested flow can also return data through a special map property called the Flow Scope.

  • Application developers can package a flow with the corresponding pages into a module, which may be distributed to a third-party developer.

  • There is a brand new scope called FlowScoped, which denotes whether a POJO is a flow-scoped bean. The annotation for this is @javax.faces.flow.FlowScoped...
