*ThemeRoller Support*
* All ACE components have been updated to support the jQueryUI [ThemeRoller|http://jqueryui.com/docs/Theming/Themeroller] theming system.
* The ThemeRoller system provides an extensive collection of ready-to-use themes, as well as an intuitive web-application for creating custom themes easily without requiring extensive CSS knowledge.
* The ThemeRoller-based CSS styles are injected into the ICEfaces page automatically. There is new "org.icefaces.ace.theme" configuration parameter to specify the ThemeRoller theme to use for the application in the web.xml. Currently supported themes are "sam" (default), and "rime" (preliminary).
* NOTE: The previous ACE component skinning approach, including CSS style-classes and class-names are no longer supported. Existing applications must be updated to use the ThemeRoller-based style classes.

*Updated & Enhanced Components*
* ace:animation has been re-implemented to use jQuery effects.
** Only standard jQuery effect types are supported. Custom transition types are no longer supported by the component.
* ace:checkboxButton, ace:linkButton, and ace:pushButton now support ThemeRoller themes.
* ace:dateTimeEntry is now based on the jQuery calendar and has the following additional enhancements:
** Supports ThemeRoller themes.
** Optionally display multiple-months in popup calendar.
** Initialize multi-month popup calendar to display Last/This/Next, This/Next/TheOneAfterThat, or any starting month desired.
** Optionally display Year / Month drop-down menus in popup calendar.
** Optionally include a "Today" button to navigate to the current date.
* ace:fileEntry now supports ThemeRoller themes.
* ace:sliderEntry has been re-implemented using the jQuery slider control.
** The showLabel attribute is currently not supported.
* ace:tabSet / ace:tabPane
** Added new "cacheOnClient" and "cacheStatically" attributes to ace:tabPane to permit maximum client-caching behavior flexibility.
** Updated to support ThemeRoller themes.

*ACE Repackaging*
* The entire Advanced Component Environment and all components have been repackaged to better isolate the ACE library from other ICEfaces framework libraries.
* Java code formerly located under the "org.icefaces.component" and "org.icefaces.generator" packages is now located under the "org.icefaces.ace" package.
* JavaScript functions formerely namespaced under the "ice.component" name-space are now under the "ice.ace" name-space.
* Any pre-existing application code that imports the ACE packages will need to be updated.

*mandatoryResource Change*
* Starting with this release the default value for the "org.icefaces.mandatoryResourceConfiguration" configuration parameter has been changed to "none".
* Previously, mandatoryResource would, by default, automatically preload all the required resources for any components found in the application classpath into the head of each new page that is rendered. This is required as it is not possible to add resources to the head dynamically in JSF 2. This resulted in applications that would continue to function even when components that were not on the original page were later added to the page dynamically. However, this convenience came at a relatively high expense in terms of additional page-loading overhead and JS processing on every page load.
* The new default behaviour for mandatoryResource is to not preload any component resources automatically. This provides the optimal efficiency in terms not loading resources that are not required on the page. This may also result in resource loading errors occurring in cases where components are initially added to a page via a dynamic update. In these cases, it is now necessary to specify a suitable mandatoryResourceConfiguration configuration parameter in the web.xml that lists the component classes that will be loaded dynamically to ensure their resources are preloaded during the initial page load.
* A new page-level mandatoryResource configuration option has been introduced in this release. By specifying the <icecore:config mandatoryResource="xxx"/> tag on the page, it is possible to tune the mandatoryResource behaviour to ensure that all required component resources are included in the initial page load. By using the page-level configuration, the mandatoryResource configuration can be optimized on a per-page basis.

*License Change*
* The Advanced Components library (icefaces-ace.jar) is now licensed under the [Apache 2.0|http://www.apache.org/licenses/LICENSE-2.0] license. This was done to better accommodate the licensing requirements of various 3rd party libraries that are used by the components (jQuery, YUI, etc.). Prior to this release it was licensed under the [Mozilla Public License (MPL) 1.1|http://www.mozilla.org/MPL/MPL-1.1.html].
* Note that all other ICEfaces 2.1 libraries (icefaces.jar, icefaces-compat.jar, and ice push.jar) continue to be licensed under the MPL 1.1 license.

{anchor:frameworkchanges}
h4. Core Framework

* Custom Update Support
** The ICEfaces Direct-to-DOM rendering engine has been enhanced to support partial component tree rendering that may consist of regular DOM-diffed regions combined with new sub-component custom update regions that are excluded from DOM differencing. This feature enables richer ACE component interactions and efficiencies for specific use-cases.

* Window Scope
** Support for @PostConstruct and @PreDestroy annotations has been added to the ICEfaces custom Window scope.

* Delta Submit Improvements
** The Delta Submit implementation has been refactored to improve efficiency and robustness.

* New messagePersistence Configuration
** New configuration parameter and icecore:config attribute have been added to support configuration of ICEfaces "intelligent message caching" feature.
** {code}<context-param>
<param-name>org.icefaces.messagePersistence</param-name>
<param-value>true</param-value>
</context-param> {code}
** Alternatively, the new <icecore:config messagePersistence="true"/> tag may be used to enable/disable message caching within a page.

* Optimizations
** Several aspects of the core framework have been optimized to reduce execution time and/or Java heap consumption.

{anchor:icepushchanges}
h4. ICEpush

* New <icecore:push group="chat"> Tag
** A new <icecore:push group=""> tag has been added to make push group registration easier.
** Multiple occurrences of this component within a view can be used to add the current view to different groups.
** Removal of expired views from the group currently relies on the automatic clean-up of the groups themselves.

* Automated ICEpush Setup/Teardown
** By default, ICEpush will now automatically setup and teardown it's blocking connection on a per-page basis, depending on whether or not any ICEPush groups are active on the page.
** Previously, ICEpush was lazily initialized, but not actively torn down if a once active push group became inactive on the page.

* New lazyPush Configurability
** A new configuration parameter has been added to disable the automated lazy initialization and teardown of ICEpush, forcing ICEpush to keep its blocking connection active at all times.
** {code} <context-param>
<param-name>org.icefaces.lazyPush</param-name>
<param-value>false</param-value>
</context-param> {code}
** There is also an attribute for the ice:config tag that allows page-level configuration. This take precedence over the context parameter setting. {code} <icecore:config lazyPush="false"/> {code}


{anchor:icechanges}
h4. ICEfaces Components

* Improved support for auto-scrolling when dragging a panelGroup inside a scrollable <DIV>.
* The ice:dataExporter now uses converters when exporting data.
* Added "partialSubmit" attribute to the ice:selectInputText component.
* Added "escape" attribute to ice:message and ice:messages.
* Added tabIndex attribute to ice:dataPaginator, ice:rowSelector/ice:datatable, and ice:panelCollapsible.


{anchor:samplechanges}
h4. Samples & Tutorials

* New Comp-Suite Sample Application
** An all-new ICEfaces Component Suite (comp-suite) sample application is introduced in this release.
** Currently features preliminary demonstrations for the new ACE components.
** Comp-Suite demo is in "preview" status and does not reflect final styling and behavior.
** The "comp-suite" sample application replaces the "ace-showcase" sample application from ICEfaces 2.0 ("ace-showcase" has been removed).


{anchor:jsfchanges}
h4. JSF Runtimes

* Apache MyFaces JSF 2.1.3
** This release provides preliminary support for ICEfaces 2 on Apache MyFaces JSF 2.1.3, and includes the MyFaces 2.1.3 libraries in the download bundles.
** See the [Known Issues|#knownissues] section for current limitations.

* Mojarra JSF 2.1.3
** This release has been tested with Mojarra JSF 2.1.3, and includes the JSF 2.1.3 library in the download bundles.


{anchor:idechanges}
h4. IDE Integrations

* NetBeans 7
** This release provides an updated IDE integration for NetBeans 7.
** NOTE: You *must* update your NetBeans 7 installation with the latest module versions prior to installing the ICEfaces 2.1 NetBeans integration. See the NetBeans Integration Release Notes for details.

* Eclipse 3.7
** This release provides an updated IDE integration for Eclipse 3.7.

{anchor:knownissues}
h2. Known Issues
----

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

h4. Wiki Documentation

* The [ICEfaces 2 Wiki documentation|http://wiki.icefaces.org/display/ICE/ICEfaces+2+Documentation] has not yet been extensively updated to reflect changes introduced in ICEfaces 2.1 Beta. This work is ongoing.

h4. General

* JSPs are not supported by ICEfaces 2.0 - use Facelets.
* It is required to specify "h:head" and "h:body" tags in your ICEfaces application pages.
* The [Delta-Submit|Configuration] function does not support cases where an Ajax DOM update in the browser dynamically introduces new form elements into the DOM that were not part of the form when the page was originally loaded. In order to use Delta-Submit successfully all form elements / components must be present on the page at the time the page is loaded.
* Due to an apparent [bug|https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=1492] in the Sun Mojarra JSF 2 runtime library, component binding is not reliable when used within a View scope.
** The recommended workaround is to use the ICEfaces "Window" or JSF "Session" scopes instead if component-binding is required. Alternatively, applications can be modified to avoid the requirement for using component-binding in View scope by using techniques similar to that used in the Data Paginator demo section of Compatible Component Showcase application. For details, see [ICE-5226|http://jira.icefaces.org/browse/ICE-5226?focusedCommentId=29297&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_29297].

h4. Advanced Components

The following Known Issues affecting the ACE Components are expected to all be resolved prior to ICEfaces 2.1 release.

* ace:accordion
** Note that ace:accordion attributes that currently reference "Tab" (TabChangeListener, OnTabChange, etc.) will be renamed PaneChangeListener and OnPaneChange in the next release.
* ace:dataTable
** Currently does not support nesting of ace:dataTables with all features.
** Currently not able to persist dataTable sort configuration settings.
** Dynamically updating the dataTable columns (changing number of columns) may not be reflected in the rendered datatable.
* ace:dataExporter
** Not exporting column headers when using column grouping.
* ace:columns
** Not supported in this release.
* ace:menu(s)
** Dynamic menus are not being re-evaluated after the initial render.

h4. MyFaces JSF

* Component Showcase (w/ MyFaces)
** Dynamic language change, data is typically "one update behind".
** ice:positionedPanel demo, only first drag works.
* Auction & Auction Monitor (w/ MyFaces)
** Both of these apps seems have an issue with the tight 1-second push loop used in those apps - they typically don't respond to clicks.
** Adjusting the <param-name>org.icefaces.sample.auction.interval</param-name> configuration parameter in the web.xml to 5000+ (5 secs) avoids the issue.
** AuctionMonitor can't close the bid box or chat.
* ICEfaces is not yet supported on Portals using MyFaces.

h4. Mojarra JSF

* Note that the Mojarra JSF 2.1.0-2.1.2 releases have several serious issues that may impact your project:
** A bug that prevents it from supporting bean-annotation on non-Glassfish 3.1 application servers and servlet containers.
** Several bugs that prevent the IE9 browser from working properly with JSF-ajax operations.
** Partial State Saving bugs that might prevent the use of Partial State Saving in your application.
* This release of ICEfaces includes the Mojarra JSF 2.1.3 release libraries which resolves the known issues noted above.
* When running a JSF application in JSF2 _PROJECT_STAGE="Development"_ mode (which is the default setting for all ICEfaces sample applications), you may see the follow warning appear at the bottom of the page: _"Form component needs to have a UIForm in its ancestry."_.
** This issue is caused by a bug in Mojarra JSF, a suggested work-around is to set the JSF2 _PROJECT_STAGE="Production"_ in the web.xml file.

h4. Browsers

* WebKit (Safari and Chrome)
** The WebKit-based browsers (Google Chrome and Apple Safari) request content-type "application/xhtml+xml" by default, which is different from virtually all other browsers. In cases where the application page doesn't set the contentType explicitly this can result in these browsers defaulting to a strict XHTML rendering mode, which can cause some unexpected styling and layout issues. In order to have WebKit-based browsers render markup consistently with other browsers, you must specify the content-type in the view tag on each page:
{code}<f:view contentType="text/html">{code}
** See http://jira.icefaces.org/browse/ICE-6138 for more information.

h4. Application Servers

* Tomcat 6.0
** In some cases, when running Tomcat on Windows, undeploying an ICEfaces 2 compatible application (i.e. that includes the icefaces-compat.jar) can cause an exception. See [http://jira.icefaces.org/browse/ICE-5222|http://jira.icefaces.org/browse/ICE-5222?focusedCommentId=27631&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_27631] for additional information about this issue. To prevent this, include a context.xml file with your application that includes the following Context attributes to prevent jar and resource locking: {code:xml}<Context antiJarLocking="true" antiResourceLocking="true"/>{code}


* Glassfish 3 / JBoss 6 (JEE 6 Platforms)
** It is necessary to have Mojarra JSF 2.1.0-FCS or greater (2.1.3 is recommended) installed. This may require updating the JSF Mojarra runtime libraries in Glassfish 3 or JBoss 6, depending on which JSF version is currently installed.
