AjaxButton and MethodBinding generated by code

Question

use jboss 4.2.2 GA with seam 2.0.2
i got a dynamic page, the components are generate by code.
i got some error with AjaxButton
the creation code is like this
HtmlAjaxCommandButton ajaxbutton = new HtmlAjaxCommandButton();
          try  {
               ajaxbutton.setId(getID("AJAXBUTTON"));
          if (map.get("action") != null && map.get("action").trim().length() > 5) {
               log.debug("action=" + map.get("action"));
               MethodBinding m = FacesContext.getCurrentInstance()
                         .getApplication().createMethodBinding(map.get("action"),
                                   null);
               ajaxbutton.setAction(m);
          if ( map.get("oncomplete")!= null) {
               log.debug("oncomplete " + map.get("oncomplete"));
               ajaxbutton.setOncomplete(map.get("oncomplete"));
          if (map.get("rerender") != null )  ajaxbutton.setReRender(map.get("rerender"));
          log.debug("value=" + map.get("Value"));
          ajaxbutton.setValue(map.get("Value"));
          catch(Exception e) {
               e.printStackTrace();
     on the console i see errors like
0:27:36,296 WARN [Interpolator] exception interpolating string: action=#{Session.editmodehinweis}
javax.el.PropertyNotFoundException: Property 'editmodehinweis' not found on type com.my.session.SessionBean
although it is there.
when i click the button the function is called!!! so why do i get this error message?

Answer 1

Once again, it is just a warning, not an error. Your code just runs, do it?
And it is certainly not related to Sun JSF. The Interpolator thing is from Seam. Just create a SSCCE and show it the JBoss boys.
