Below are the changes that were made since the last early access release, OpenFaces 2.0 EAP2. Please take a look at the What's New in OpenFaces 2.0 document if you'd like to see all changes since the last 1.x release.

New Components

• CompositeFilter – allows the user to build complex filter crieteria with multiple filter conditions. Works as a standalone component or can be bound to DataTable/TreeTable components to filter their data.
  
• LayeredPane – a container that allows switching between different sets of displayed components.
• SelectOneRadio – an extended version of the standard <h:selectOneRadio> component, which provides additional styling options and makes it possible to customize radio buttons with images.
  
• SelectManyCheckbox – an extended version of the standard <h:selectManyCheckbox> component, which provides additional styling options and makes it possible to customize radio buttons with images.
• CommandButton – an extended version of the standard <h:commandButton> which includes the Ajax features and an ability to customize button's content with sub-components or HTML.
• CommandLink – an extended version of the standard <h:commandLink> which includes the Ajax features.

Enhancements

• Ajax settings:
• • It's now possible to customize Ajax progress message position with new horizontalAlignment/verticalAlignment attributes of <o:defaultProgressMessage> tag.
  • Ajax progress message can now be made semitransparent and shown with a smooth transparency transition (see <o:defaultProgressMessage> tag documentation).

  • Added support for interactive column visibility customization. See the Displaying Column Menus section in DataTable and TreeTable documentation for details.
  • Numerous filtering enhancements, see the "DataTable/TreeTable Filtering Enhancements" section below.
  • Added support for specifying a popup menu for table columns, containing either the standard or customized set of actions. See the Displaying Column Menus section in DataTable and TreeTable documentation for details.
  • Added header and footer attributes to all column tags to serve as a convenient replacement for specifying the text in the "header" and "footer" facets.
  • Significantly simplified handling large data sets using Hibernate library. See the Using DataTable with the Hibernate Library section in DataTable documentation for details.
  • There's a new "subHeader" facet in the column tags for DataTable and TreeTable components that allows customizing the contents that appear in the table's header section under the column headers.

  • All popups in components like DropDownField, SuggestionField, Calendar, DateChooser, PopupMenu can now be closed by pressing Esc key.
  • Added support for handling mouse events in <o:floatingIconMessage> tag.
  • Extended client-side API for PopupMenu, Window and PopupLayer components with methods isVisible(), getLeft(), and getTop().
  • Improved error checking when processing default validation message presentation parameters in web.xml.

Ajax Framework Changes

The Ajax Framework API has been significantly modified and extended to make it consistent with the JSF 2.0 API. Tags and attributes have been renamed in accordance with the new specification. Please refer to the "Migrating to the New Ajax API" sub-section in the Migrating from OpenFaces EAP2 document.

New features have been added to the Ajax (former ReloadComponents) component:

• It's possible to specify JavaScript code that should be executed on the client when an event defined by event attribute occurred (onevent attribute);
• New attribute disabled now indicates whether or not the component should render client script on referred component.
• Ajax component now automatically decides when to disable the default action of the attached component to avoid the conflict between Ajax action and the default action of the attached component (disableDefault attribute removed).

DataTable/TreeTable Filtering Enhancements

The filtering API for DataTable and TreeTable components has been significantly reviewed and enhanced. The previous filtering API consisted of filtering-related attributes in <o:column> tag. Although this was enough for a simple API, different kinds of filters require different sets of attributes and additional features require much more attributes, so filters are now organized as separate tags – one tag per one type of filter: <o:inputTextFilter>, <o:dropDownFieldFilter>, and <o:comboBoxFilter>. Each tag has a set of attributes applicable for that particular type of filter. It's quite easy to migrate to the new API though, see the "Migrating to the New Filtering API" sub-section in the Migrating from OpenFaces EAP2 document.

Here are the new features that were implemented as part of the new API:

• It's possible to customize whether search should be case sensitive or not.
• It's now possible to customize the condition by which search has to be performed (contains, equals, less, greater, etc.).
• It's now possible to specify style and all other component-specific attributes of filtering components.
• There's now an option (turned on by default) that makes filtering to be performed on the fly as the user types in the filter field.
• DropDownFieldFilter now suggests filter text as the user types it.
• Filters can now be placed outside of their DataTable/TreeTable components.
• The filtering expression can now be detected automatically when a filter resides in a table column.

Please see the Filtering section in the DataTable and TreeTable documentation for the comprehensive details on featurs and usage of the filtering functionality.
