JSF navigation determines the web application flow from one JSF page to another. Navigation takes place when the user clicks on a JSF navigation tag. In a JSF page these tags have the following form:

     <nav-tag value="label-expression" action="outcome-expression"/>
      

The "JSF Navigation Tags" menu item describes the tags that can be used for nav-tag.

The outcome-expression is a string-valued expression:

• Its value is called an outcome, which can be either static or dynamic.
• An outcome is eventually translated into a view id, which identifies the JSF page that is displayed after the button is clicked.
