This is to aid integration with CDI (JSR-299) implementations, which are require a callback when EL expression evaluation completes; the necessary hook into EL is via the ExpressionFactory. Adding ExpressionFactory to this list would make implemetors have to jump through fewer hoops to obtain the callback [1].<br> <br> I propose this change to the MR so it can be used in the EE6 platform, the target for JSR-299.<br><br> Changes to spec required<br> -----------------------------------<br><br> * Add ExpressionFactory to the list of classes required to support the decorator pattern<br> * Add ExpressionFactoryWrapper class to support the decorator pattern<br><br> Changes to implementation required<br> --------------------------------------------------<br><br> * Add support for exposing and using wrapped ExpressionFactory<br><br> Impact on users and frameworks<br> --------------------------------------------<br><br> Users can now:<br><br> * call application.setExpressionFactory(new WebBeansExpressionFactory(application.getExpressionFactory());<br> * configure a wrapping expression factory in faces-config.xml<br> <application><br> <expressionFactory>org.jboss.webbeans.el.WebBeansExpressionFactory</expressionFactory><br> </application><br><br> [1] Currently this is possible by wrapping the application via the application factory and overriding the getExpressionFactory method<br></blockquote></div><br><br clear="all"><br>-- <br>Dan Allen<br>Senior Software Engineer, Red Hat | Author of Seam in Action<br>Registered Linux User #231597<br><br><a href="http://mojavelinux.com">http://mojavelinux.com</a><br><a href="http://mojavelinux.com/seaminaction">http://mojavelinux.com/seaminaction</a><br><a href="http://in.relation.to/Bloggers/Dan">http://in.relation.to/Bloggers/Dan</a><br> </html>
