Component j_id22 not instance of org.richfaces.component.UID

[nevez]

Hello, i`m trying to create richfaces components dynamically:

import org.jboss.seam.annotations.Name;
import org.richfaces.component.UIDropDownMenu;
import org.richfaces.component.html.HtmlDropDownMenu;
import org.richfaces.component.html.HtmlMenuItem;

@Name("confTypeMenu")
public class ConfTypeMenu {

 public UIDropDownMenu getMyMenu() {
 UIDropDownMenu menu = new HtmlDropDownMenu();
 HtmlMenuItem menuItem = new HtmlMenuItem();
 String subOption = "Sec. Change Passsword";
 menuItem.setValue(subOption);

 menu.getChildren().add(menuItem);
 return menu;

 }

and using it in my .xhtml:

 <rich:dropDownMenu binding="#{confTypeMenu.myMenu}"/>

and i get the following error when trying to acces page:

Component j_id22 not instance of org.richfaces.component.UIDropDownMenu

i`m using JBoss AS 4.2.1, and JBoss Seam 2.0.0

any ideas ?
TIA

I think you should use

HtmlDropDownMenu menu = new HtmlDropDownMenu();

and return type should be HtmlDropDownMenu as it is shown in Developer Guide (see 6.41.4. Creating the Component Dynamically Using Java)

I tried, but it doesn`t work, could there something be wrong with classloading ?
I find out that jboss-service.xml should have a UseJBossWebLoader property, but i cant find the property anywhere and where to put it.

I solved the problem, as i suspected there was a problem with classloading, in \jboss-4.2.0.GA\server\default\deploy\jboss-web.deployer\META-INF\jboss-serice.xml
i changed "UseJBossWebLoader" to true and used the following code to create component:

private HtmlDropDownMenu menu;
public HtmlDropDownMenu getMyMenu() {
 if (menu == null) {
 Application app = FacesContext.getCurrentInstance().getApplication();

 menu = (HtmlDropDownMenu) app.createComponent(HtmlDropDownMenu.COMPONENT_TYPE);
 menu.setValue("File");
 .....
 }
 return menu
}
