10g UIX UIExtensions

Question

This is sort of a followup to a UIX thread: Refer to 'parent' 'uix.current'?
The extension I posted there appears to be working, but the compiler always complains that it is 'unable to parse binding' on my UIExtension classes. It's just a warning, and the code still compiles and works, but is there a way to avoid the warning?
Also, I wrote another extension for accessing attributes, for which I'll post the code below. I know that objects like 'sessionScope' are available in a UIX page, but without a 'set' like in JSTL, is there another way to set values on the scope objects, short of an extension like below?
Also, if someone could please respond to my question about a place to put the el expressions for my extensions. Currently, I put the 'setter' calls in a text tag, since the setters are void, so the tag doesn't render.
Finally, will there be a 'set' and temporary variables in the production 10g?
public class ScopeAttributeAccessorUIExtension implements UIExtension  {
     public static final String ACCESSOR_NAMESPACE = "http://uix.avega.com/access";
     public void registerSelf(ParserManager parserManager) {
          XMLUtils.registerFunctions( parserManager, ACCESSOR_NAMESPACE, ScopeAttributeAccessor.class );
     public void registerSelf(LookAndFeel lookAndFeel) {
public class ScopeAttributeAccessor  {
     public static void sessionSet( UIImplicitObject uix, String key, Object value ) {
          RenderingContext context = uix.getRenderingContext();
          BajaContext bajaContext = BajaRenderingContext.getBajaContext( context );
          HttpServletRequest request = bajaContext.getServletRequest();
          HttpSession session = request.getSession();
          session.setAttribute( key, value );
     public static Object sessionGet( UIImplicitObject uix, String key ) {
          RenderingContext context = uix.getRenderingContext();
          BajaContext bajaContext = BajaRenderingContext.getBajaContext( context );
          HttpServletRequest request = bajaContext.getServletRequest();
          HttpSession session = request.getSession();
          return session.getAttribute( key );
     public static void requestSet( UIImplicitObject uix, String key, Object value ) {
          RenderingContext context = uix.getRenderingContext();
          BajaContext bajaContext = BajaRenderingContext.getBajaContext( context );
          HttpServletRequest request = bajaContext.getServletRequest();
          request.setAttribute( key, value );
     public static Object requestGet( UIImplicitObject uix, String key ) {
          RenderingContext context = uix.getRenderingContext();
          BajaContext bajaContext = BajaRenderingContext.getBajaContext( context );
          HttpServletRequest request = bajaContext.getServletRequest();
          return request.getAttribute( key );
}

We don't have any special integration with xsql, but you can include non-uix content using urlInclude and servletInclude. See the section "Including JSP, Servlet, and Other HTML Content" in "Building J2EE Applications -> Working with the web tier -> Working with ADF UIX Pages -> UIX Guidelines -> Dynamic User Interfaces -> Includes and Templating in ADF UIX".
