Announcement: Liferay Faces 4.2.0-beta Released

On April 28, 2015 Liferay released Liferay Faces 4.2.0-beta:

Liferay Faces 4.2.0-beta JSF 2.2 + Liferay Portal 6.2 Release Notes

Feature Complete

This new version of Liferay Faces is just about 100% feature complete which is why we decided to advance the version from "milestone" to "beta" status.

New Showcase Components

The Liferay Faces Showcase is hosted at and features a suite of new Java-based JSF components, many of which utilize AlloyUI and can be used in either webapps or portlets. Here is a list of the new components that have been developed since our 4.2.0-m2 release back in September, 2014:

For more information about our new Component Suite, see Juan Gonzalez' blog post titled New Liferay Faces release - Portal components and Vernon Singleton's blog post titled New Liferay Faces release - The alloy:accordion component.

Support for PrimeFaces 5.2

Thanks to our technology partnership with PrimeTek Informatics, we were able to resolve several portlet-related compatibility issues with PrimeFaces. In addition, we upgraded the new primefaces5-portlet and primefaces5-users-portlet demos to PrimeFaces 5.2.

Download Instructions

Since the 4.2.0-beta release is not General Availability (GA), the JAR artifacts are *not* published at Maven Central. Instead, they are published at the new Liferay Previews Nexus Repository along with the demo portlets.

Version Scheme

Please refer to the Liferay Faces Version Scheme wiki article for a detailed explanation of the version numbering.


This 4.2.0-beta release is a technology preview that is suitable for development purposes but should not be used in a production environment. It will not be supported under the Liferay EE subscription until it reaches GA (General Availability) status.

Support For JSF 2.2 and Liferay Portal 6.2

  • This release of Liferay Faces is compatible with JSF 2.2

  • If deploying portlets to Liferay Portal 6.2, then developers should read the new Migrating From Liferay Faces 3.1 to Liferay Faces 3.2/4.2 section in the Developer's Guide. Specifically, JSF portlets require the following option in the WEB-INF/liferay-portlet.xml descriptor: <requires-namespaced-parameters>false</requires-namespaced-parameters>

Tomcat 7 Only

Developed under JSR 344, JSF 2.2 is part of the larger Java EE 7 specification from the JCP. Even though Java EE 7 includes technologies like CDI 1.1 and Servlet 3.1, JSF 2.2 only depends on Java EE 6 technologies like CDI 1.0 and Servlet 3.0. This means that JSF 2.2 webapps and portlets can be deployed in Java EE 6 (Servlet 3.0) servlet containers such as Tomcat 7. However, Java EE 6 full-profile application servers such as GlassFish 3.2, JBoss 7.1, and WebLogic 12c bundle JSF 2.1 and cannot be upgraded to JSF 2.2. At the time of this writing, Liferay, Inc. has not released any Liferay Portal 6.1/6.2 bundles with Java EE 7 servers such as Tomcat 8, GlassFish 4.0 or JBoss/WildFly 8. Therefore this milestone has only been tested for compatibility with Liferay Portal 6.1/6.2 on Tomcat 7.


The Liferay Faces team is hard at work adding new components and new features so that we can achieve Release Candidate (RC) status in our next release. Stay tuned!
