Faces Flows is a new JSF 2.2 feature that defines a scope that can span several pages. Flow scoped beans are created when the user enters a flow (a set of web pages) and are destroyed when the user leaves the flow.
Faces Flows adopts the convention over configuration principle of JSF. The following conventions are typically used when developing applications employing Faces Flows:
-flowmust exist inside the directory that contains the pages in the flow (the file may be empty, but it must exist)
