Errors in faces-config after upgrade to JSF 2.2

Question

After upgrading the JSF implementation in our project from Myfaces 1.1 to MyFaces 2.2.12, my IDE (IntelliJ) shows me errors for all navigation-rule and managed-bean entries in my faces-config.xml. I have changed the root element in that file from

<!DOCTYPE faces-config PUBLIC
        "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN"
        "http://java.sun.com/dtd/web-facesconfig_1_0.dtd">

<faces-config>

to

<faces-config
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
    version="2.2">

navigation-rule entries like the following used to work and didn't show any errors before the upgrade:

<navigation-rule>
    <navigation-case>
        <from-outcome>exampleOutcome</from-outcome>
        <to-view-id>/newpages/view1.jsp</to-view-id>
    </navigation-case>
</navigation-rule>

After the upgrade to JSF 2.2, the navigation-case element is error-marked with a red underline. When hovering the text with the mouse, I get the error message:

Invalid content was found starting with element 'navigation-case'. One of '{"http://xmlns.jcp.org/xml/ns/javaee":from-view-id}' is expected.

Does this mean the from-view-id has become obligatory with JSF 2.2?

managed-bean entries like

<managed-bean>
    <managed-bean-name>ExampleBean</managed-bean-name>
    <managed-bean-class>my.example.package.ExampleBean</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

produce the similar error message:

A field of identity constraint 'faces-config-managed-bean-name-uniqueness' matched element 'faces-config', but this element does not have a simple type.

I haven't found anything about structural changes like this becoming necessary with the upgrade to JSF 2.2. Interestingly, I didn't get this error with an intermediate change to JSF 2.1!

Could anyone point me in a direction that might help this problem?

Answer 1

Try this :

<?xml version="1.0" encoding="UTF-8"?>
<faces-config


xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
version="2.2">
<navigation-rule>
    <display-name>first_page.xhtml</display-name>
    <from-view-id>/first_page.xhtml</from-view-id>
    <navigation-case>
        <to-view-id>/second_page.xhtml</to-view-id>
    </navigation-case>
</navigation-rule>

Answer 2

You have to insert an empty tag <from-view-id></from-view-id> before <navigation-case>.

Example:

<navigation-rule>
    <from-view-id></from-view-id>
    <navigation-case>
        <from-outcome>go_start</from-outcome>
        <to-view-id>/pages/start.xhtml</to-view-id>
    </navigation-case>
</navigation-rule>
