JSF navigation problem
My faces-config.xml is like that:
<managed-bean>
<managed-bean-name>manufacturer</managed-bean-name>
<managed-bean-class>controller.ManufacturerController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
<navigation-rule>
<navigation-case>
<from-outcome>list_manufacturer</from-outcome>
<to-view-id>faces/list.jsp</to-view-id>
</navigation-case>
<navigation-case>
<from-outcome>login_failure</from-outcome>
<to-view-id>faces/main.jsp</to-view-id>
</navigation-case>
</navigation-rule>
and my controller class is:
publicclass ManufacturerController{
private Manufacturer manufacturer;
public String list(){
this.manufacturer =new Manufacturer();
return"list_manufacturer";
}
}
in index.jsp, I call list method when Liste button is clicked:
<f:view>
<h:form>
<h1><h:commandButton value="Liste" action="#{manufacturer.list}"/> </h1>
</h:form>
</f:view>
But when I run the application I get this error:
HTTP Status 500 -
type Exception report
message
descriptionThe server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: javax.faces.component.UIViewRoot cannot be cast to com.sun.faces.application.StateManagerImpl$TreeNode
root cause
java.lang.ClassCastException: javax.faces.component.UIViewRoot cannot be cast to com.sun.faces.application.StateManagerImpl$TreeNode
note The full stack traces of the exception and its root causes are available in the Sun Java System Application Server 9.1 logs.

What do you think about this?
