Sell Item JSF - A Spring Web Flow Sample

Sell Item (launch with a JSF command link)

Sell Item (launch with a regular anchor tag)

This Spring Web Flow sample application is the JSF-based version of the familiar "Sell item" sample. It illustrates the following concepts:

• Using Spring Web Flow with JSF
• Implementing a wizard using web flows.
• Use of conversation scope.
• Using expressions to apply dynamic flow navigation rules
• Using continuations to make the flow completely stable, no matter how browser navigation buttons are used.
• "Always redirect on pause" to benefit from the POST+REDIRECT+GET pattern with no special coding.
• Using "conversation invalidation after completion" to prevent duplicate submits of the same sale while taking advantage of continuations to allow back button usage while the application transaction is in process.
