Completed enhancements to the Tag Registry and Component Tree Views

    See here for information on Alternative View Handler support

    Tag Registry View

    The Tag Registry View allows a JSF user to browse the JSF tags declared in each project including information about what components, converters and validators they create at runtime.

    Component Tree View

    The Component Tree View allows a user to browse a design-time approximation of what a view (i.e. a JSP page or Facelet XHTML) will look like at runtime. This component tree will also be used by an increasing number of component-based features in the future.

    The Source tab of the Web Page Editor (WPE) supports Hyperlink on a Managed Bean variable, Managed Bean property and Managed Bean method referenced in the Expression Language(EL) of a tag-attribute. Users can (Ctrl+click) on the hyperlink to navigate to the source of the Managed Bean.


Hover Help support in WPE's Source tab

    The Source tab of the Web Page Editor (WPE) provides Hover Help on all symbols defined in the Expression Language(EL) of a tag-attribute including references to Managed Beans and Resource Bundles.

New EL framework enhancements

    Thanks to Xiaonan Jiang at IBM for driving new framework requirements and providing prototypes.

    Decorative Variable and Property Resolvers

    To better support the decorative nature of JSF variable and property resolvers, we have added the ability to register decorative design time resolvers to the default application manager. Decorative resolvers are called only if the runtime resolver that they are associated with is found in the configuration of the current web project. For more information see: here

    Enhancements to symbol creation API

    We have refactored several internal symbol creation methods and combined them with contributions by Matthias Fuessel and Xiaonan Jiang (IBM), to create a new set of extension points to simplify creation of common JSF symbols. See here for more details.

    We have also made the symbol creation methods available on a new factory called JSFSymbolFactory.

New EL validation preferences

    New validation preferences for EL validation problems allow you to change the severity of type assignment problems between Error, Warning and Ignore.
