This Spring Web Flow sample application is the JSF-based version of the familiar "Sell item" sample.
It illustrates the following concepts:
</p>
<ul>
<li>Using Spring Web Flow with JSF</li>
<li>Implementing a wizard using web flows.</li>
<li>Using continuations to make the flow completely stable, no matter how browser navigation buttons are used.</li>
<li>
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. </li>
<li>"Always redirect on pause" to benefit from the POST+REDIRECT+GET pattern with no special coding.</li>
<li>Using <A href="http://www.ognl.org/">OGNL</A> based conditional expressions.</li>
<li>Use of subflows to compose a multi-step business process from independently reusable modules.</li>
