Note: This issue is also being tracked at the Liferay issue tracker under [FACES-2867|https://issues.liferay.com/browse/FACES-2867].

h3. Problem Description:

The BridgeSetup.java and BridgeFormsSetup.java classes assume that the "org.icefaces.impl.event::ViewState" attribute will always be be non-null. Because of this assumption, NullPointerException is being thrown in a portlet environment during a portlet mode change. This is because of a requirement in JSR 329/378 that prevents "non excluded" request attributes from surviving from the ACTION_PHASE of the portlet lifecycle into the RENDER_PHASE of the portlet lifecycle during a portlet mode change. This functionality is implemented in Liferay Faces Bridge with the following code:
{code:java|title=BridgeRequestScopeImpl.java}
if (!portletMode.equals(portletRequest.getPortletMode())) {
setPortletModeChanged(true);
restoreNonExcludedRequestAttributes = false;
}
{code}

h3. Steps to Reproduce:

1. Download and extract the [Pluto 3.0.0 Tomcat bundle|https://portals.apache.org/pluto/download.html].

2. Download the [Mojarra 2.3.0-m10 all-in-one jar|http://search.maven.org/remotecontent?filepath=org/glassfish/javax.faces/2.3.0-m10/javax.faces-2.3.0-m10.jar]:
{code:xml}
<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.faces</artifactId>
    <version>2.3.0-m10</version>
</dependency
{code}

3. Extract the jar:
{noformat}jar xf javax.faces-2.3.0-m10.jar{noformat}

4. Remove the following file:
{noformat}rm META-INF/services/javax.servlet.ServletContainerInitializer{noformat}

5. Re-zip the jar:
jar cmf META-INF/MANIFEST.MF javax.faces-2.3.0-m10-fixed.jar META-INF/ com/ javax/

6. Copy the jar to Pluto's tomcat/lib folder

7. Copy the icefaces-applicant-portlet (attached) war to Pluto's tomcat/webapps folder

Note: The icefaces-applicant-portlet demo is part of the Liferay Faces suite of demo portlets. Its purpose is to exercise several typical use-cases of ICEfaces in a portlet environment.

8. Start Pluto's Tomcat

9. Visit the following URL:
http://localhost:8080/pluto/portal

10. Using the Pluto Admin page, create a new page named "icefaces" and add the portlet named "1" from the com.liferay.faces.demo.icefaces.applicant.portlet module.

11. Visit the following URL:
http://localhost:8080/pluto/portal/icefaces

12. Click on the "Edit" link under the "Liferay" logo in the upper right hand corner.

13. Click the Submit button

(/) Expected Results
The portletViewMode.xhtml view is rendered correctly.
