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

@Stateful
@Name("dragen")
@Scope(ScopeType.SESSION)
public class DragenAction implements Dragen {
private org.richfaces.component.html.HtmlSeparator Separator = new org.richfaces.component.html.HtmlSeparator();
.....
public org.richfaces.component.html.HtmlSeparator getSeparator() {
return Separator;
}

....

and using it in my .xhtml:

 <rich:separator binding="#{dragen.separator}" />

and i get the following error when trying to acces page:
Component formTableData:j_id22 not instance of org.richfaces.component.UISeparator

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

any ideas ?
