i 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?
