Faces Flows
Faces Flows 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 Jakarta Faces. The following conventions are typically used when developing applications employing Faces Flows:
- All pages in the flow must be placed in a directory whose name defines the name of the flow.
- An XML configuration file named after the directory name and suffixed with
-flowmust exist inside the directory that contains the pages in the flow (the file may be empty, but it must exist) - The first page in the flow must be named after the directory name that contains the flow
- The last page in the flow must not be located inside the directory containing the flow, and must be named after the directory name and suffixed with
-return
