What's New in 4.0?


ICEfaces 4.0 is a major version release and as such adds, removes, and changes a significant number of features and APIs.

The most significant change is that the legacy ICE (Compat) components have not been brought forward into the 4.0 release. Most of these components rely on an earlier ICEfaces Direct-to-DOM rendering technique that isn't compatible with many newer JSF features, such as partial-page rendering (f:ajax). Rather than invest the engineering resources to bring these up to spec for JSF 2.2, we decided to focus our energies on further evolving the newer ACE and MOBI components. Existing applications that use those components will need to be migrated to use the ACE and/or MOBI components.

Existing ICEfaces applications will need some degree of adaptation to work correctly with this release, the scope of which will depend on the specific features and components that they leverage from prior ICEfaces releases.

See the ICEfaces 3 to 4 Migration Guide Wiki for more information.

ACE Components

See the ACE Components Wiki for reference documentation on these components.
  • Reduced JavaScript resource footprint and optimization, only loads the resources you need for the components you are using.

New Components:

  • ace:audioPlayer
  • ace:buttonGroup
  • ace:dynamicResource
  • ace:growlMessages
  • ace:graphicImage
  • ace:qrcode
  • ace:radioButton

The "activate" event will continue to function as an alias to the new "action" event for backwards compatibility: ace:checkboxButton, ace:dataExporter, ace:linkButton, ace:menuItem, ace:printer, ace:pushButton, ace:radioButton.
      • Changed the default execute scope to "@this" instead of "@all" for the following components/events: ace:linkButton/action, ace:maskedEntry/valueChange, ace:menuItem/action, ace:printer/action, ace:pushButton/action, ace:radioButton/action, ace:autoCompleteEntry, ace:richTextEntry, ace:menuItem.

ICEfaces Framework

ICEfaces Core (ICECORE) Components

See the CORE Components Wiki for reference documentation on these components.
  • New icecore:focusManager
  • New icecore:loadBundle
  • New icecore:idleMonitor
  • New icecore:jsEventListener

Core Framework

See the ICEfaces Core Framework Wiki for details on the topics listed below.
  • New "org.icefaces.redirectOnExceptionMapping" configuration parameter to support redirecting users to specific pages for different exception types.
  • Added support for the "sessionExpiredRedirectURI" config param.
  • Added ability to configure the base path of an application.
  • The 'org.icefaces.generateHeadUpdate' configuration is now "true" by default. This supports loading component resources into the HEAD of the page dynamically, thus removing the requirement to use mandatoryResource Configuration to pre-load component resources.)
  • New client-side JavaScript API for user-inactivity detection (can be used with or without the icecore:idleMonitor tag).
  • New client-side pending session-timeout warning event and dialog.
  • New ability to specify "load only" dependency configuration for resources in application resource-dependency.xml file.
  • Support for JSF 2.2 f:ajax resetValues.
  • Support for HTML5 pass-thru attributes.
  • Support resource coalescing in portlet environments.
  • Added optional support for JSF Parameter Namespacing.
    • Primarily used for Portlets at this time, requires Mojarra JSF 2.2.7+ and Liferay 6.2+, and associated LiferayFacesBridge.
  • Enhanced PortableRenderer and supporting classes to allow push group registration and de-registration of views associated with the current session.
  • The faces-config.xml resources have been named to allow ordering of resources.
  • Improved the performance of client-side component resources cleanup via pre-determination of resources requiring cleanup on the server during DOM processing.


See the ICEpush Wiki for details on the topics listed below.
  • ICEpush now leverages HTML5 browser local-storage for inter tab/window communication, instead of cookies.
  • New Cloud Push JavaScript API.
  • Now supports a configurable push delivery time-window that results in push updates being delivered within a window of time. This provides the ability to tune update frequency to moderate server load and improve application responsiveness.
  • Added new callback listeners to NotificationProviders and the BlockingConnectionServer.
  • New configuration parameters to tune push-storm detection ("org.icepush.notificationStormLoopInterval" and "org.icepush.notificationStormMaximumRequests").
  • Initialization of the ICEpush blocking connection now occurs after the document is completely loaded to avoid possible interference with JavaScript component loading and initialization.


  • ICEfaces Desktop & Mobile Showcase
    • Enhanced Desktop Showcase
      • Includes demos for all ACE and ICECORE components, grouped by component type.
      • Now supports searching for demos based on partial component name, description text, or "common" alternative names.
      • Now uses partial-page rendering when navigating to each demo for increased responsiveness.
      • Each individual demo is now bookmarkable and can be navigated to directly via its URL.
    • New Mobile Showcase
      • A new Mobile Showcase page has been added to demonstrate the new MOBI adaptive-layout containers and components.
      • This sample is best viewed on a mobile device, but HTML5-desktop browsers can also be used.
      • Note that the MOBI "Native" components require the BridgeIt mobile app. to function, thus, may only be used on a supported mobile device.
  • Auction Monitor
    • The compat/auction-monitor sample has been removed from this release as it relied on the ICE components, which are no longer supported.

IDE Support

  • ICEfaces 4 does not require specialized IDE integration bundles, but rather can be used directly with leading JSF 2.2-supporting IDEs.
  • New IDE tutorials are available to explain the steps required to configure your NetBeans 8.x or Eclipse 4.4 IDE projects for ICEfaces 4.0: IDE Tutorials for NetBeans and Eclipse

JSF Runtimes

  • Mojarra JSF has been updated to v2.2.7 in this release.
  • MyFaces JSF has been updated to 2.2.5 in this release.

Known Issues

The following section describes the most commonly encountered known issues with this release:


  • Client state saving mode is not supported by ICEfaces - it is required to use SERVER state saving mode.
  • It is required to specify "h:head" and "h:body" tags in your ICEfaces application pages.
  • Applications must avoid the use of "javascript: void(0)" in browser DOM event handlers as this technique causes the "onBeforeOnload" event handler to be called in IE, which results in the ICEfaces bridges shutting down (thinking that the page is being navigated away from).


  • The following standard "h:" components are not supported by the deltaSubmit feature (due to a problematic rendering technique that they utilize):
    • h:selectOneMenu
    • h:selectManyMenu
    • h:selectOneListbox
    • h:selectManyListbox
  • The work-around is to use similar alternative components instead, such as ace:simpleSelectOneMenu, or ace:list.


  • ICEpush (icepush.jar) asynchronous update support is limited to a single ICEfaces application per host-name/server.
    • Viewing multiple ICEfaces applications in the same browser from the same host server concurrently will result in only one of the applications having functional push capabilities.
    • Support for pushing asynchronous updates to multiple ICEfaces applications from the same server/host-name requires the use of the Enterprise Push Server (EPS), which is included in ICEfaces EE (Enterprise Edition).
    • This is necessary because the browser cannot support multiple concurrent push connections, so all push traffic must be multiplexed at a single point on the server.

JSF Runtimes

  • This release requires JSF 2.2+. JSF 2.1 runtimes are not supported.
  • Note that Mojarra JSF 2.2.8 is not supported in this release (see ICE-10335 for details). JSF 2.2.7 is the latest Mojarra release certified with ICEfaces 4.0.


  • The following features rely on HTML5 support in the browser, and are not supported on IE8 or IE9:
    • All MOBI components
    • icecore:navigationNotifier
    • ace:audioPlayer and ace:videoPlayer
    • ace:textEntry "secret" mode is not supported on IE8.

Sample Applications

  • Many of the Desktop Showcase ACE demo .xhtml source files erroneously contain the following extraneous namespace declaration: xmlns:ice="". This will cause no problems in terms of execution, however, many IDEs will flag this as a warning when the namespace cannot be resolved. Workaround is to ignore the warnings or remove the entries - this will addressed in the next release.
