Navigation to other nodes within a flow can occur normally, by simply placing the name of the node that
you want to navigate to next within the
action
attribute of a command component. Optionally, navigation can be
definition within the flow configuration, via either code or XML. We will discuss navigation more in the following
sections. The next lines of code show you what
intermediateFlow.xhtml
looks like.

To determine when a flow will exit, either navigate to a view that resides outside of the flow using standard JSF
navigation or specify an element entitled
<faces-flow-return> in the
flow definition. This
<faces-flow-return>
element can contain a
<navigation-case>
that will lead to the exit of the flow. For example, the following demonstrates
a single exit navigational case for a flow:
<faces-flow-return id="intermediateFlow">
<navigation-case>
<from-outcome>nextViewNode</from-outcome>
</navigation-case>
</faces-flow-return>
