Calling JavaScript from a Managed Bean

A frequent request we got for ADF Faces in previous releases is for a method that allows developers to call JavaScript functions on a page from a managed bean. Trinidad implemented an API for this and because ADF Faces RC is based on Trinidad, this functionality now becomes available in ADF FAces as well

ExtendedRenderKitService service = Service.getRenderKitService(facesContext, ExtendedRenderKitService.class);
service.addScript(facesContext, "alert('foo');");

Note that calling a JavaScript method may fail if the command component uses PPR.
