Issue with rich:orderingList

Hi
I get the following exception while submitting the page with an ordering list

sourceId=j_id16:localelist[severity=(ERROR 2), summary=("Component j_id16:localelist has invalid value expression com.rim.webservices.apps.sdownloads.model.LocalizedSite@8de88a"), detail=("Component j_id16:localelist has invalid value expression com.rim.webservices.apps.sdownloads.model.LocalizedSite@8de88a")]

xhtml
*********
<rich:orderingList id="localelist" converter="siteConverter" orderControlsVisible="false" fastOrderControlsVisible="false" value="#{siteAction.localizedSites}" var="loc" listHeight="100" listWidth="150" selection="#{siteAction.selectedLocaleList}">
                       <rich:column width="180">
                         <h:outputText value="${loc.language.name}" ></h:outputText>
                       </rich:column>
                     </rich:orderingList>

Converter
***********
public Object getAsObject(FacesContext context, UIComponent component, String value)
{
       LocalizedSite ls = new LocalizedSite();

      if (value == null || (value.trim().length() == 0))
      {
          return value;
      }
      Language l = new Language();
      l.setName(value);
      ls.setLanguage(l);

      return ls;
}

public String getAsString(FacesContext context, UIComponent component, Object value)
{
       LocalizedSite ls = null;

      if (value instanceof LocalizedSite)
      {
           ls = (LocalizedSite)value;

          StringBuilder lsAsString = new StringBuilder();
          lsAsString.append(ls.getLanguage().getName());
          return lsAsString.toString();
      }
      return "";
}

Please help if anybody got a solution for this.

I had same problem. For me, my entity was implementing hashCode and equals generated from ECLIPSE!!! and I was just using the id field for equality, but for some reason, that broke it all :(.

     @Override
     public int hashCode() {
          final int prime = 31;
          int result = 1;
          result = prime * result + ((id == null) ? 0 : id.hashCode());
          return result;
     }

     @Override
     public boolean equals(Object obj) {
          if (this == obj)
               return true;
          if (obj == null)
               return false;
          if (getClass() != obj.getClass())
               return false;
          Question other = (Question) obj;
          if (id == null) {
               if (other.id != null)
                    return false;
          } else if (!id.equals(other.id))
               return false;
          return true;
     }
