Problem
A global navigation rule is a rule that applies to all pages. For example, apply a “logout” navigation rule that every pages are allow to access. Is there a way to configure it in JSF?
Solution
In JSF, wildcard is supported in navigation rule, you can use a “*” to specify a navigation rule that applies to all pages.
<navigation-rule>
<from-view-id>*</from-view-id>
<navigation-case>
<from-outcome>logout</from-outcome>
<to-view-id>logout.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
In this example, all the pages in your web application is able to access the “logout” navigation.
See another example,
<navigation-rule>
<from-view-id>/customer/*</from-view-id>
<navigation-case>
<from-outcome>validation</from-outcome>
<to-view-id>customer-validation.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
This rule applies to all pages that start with the prefix /customer/.
Note
The “*” wildcard functionality is limited in JSF, because only one “*” is allowed, and it must be at the end of the “form-view-id” string. For example,

It works.
<from-view-id>/customer/*</from-view-id>
It will never match…
<from-view-id>/cus*mer/</from-view-id>
<from-view-id>/c*sto*er/*</from-view-id>
<from-view-id>*/customer</from-view-id>

Its from-view-id.
I’m new to JSF and I got confused whether its form and from.
BTW the article is clear and crisp and easily understandable.
Thank you.
