Hi all!

Im just trying to go to another page, so i did it in my login.jsp:


and I set in the faces-config the following code:

<navigation-rule>
<from-view-id>/login.jsp</from-view-id>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/home.jsp</to-view-id>
</navigation-case>
</navigation-rule>


When I click in the "submit" button I got the folowing exception:

exception
javax.servlet.ServletException: Expression cannot be null;

root cause:
javax.el.ELEexception: Expression cannot be null.

Anyone have tips of why this error is occurring??


Tk you very much!
