hi,
here you have an example:

package es.rbcdexiais.boleta.converters;

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.persistence.EntityManager;
import javax.persistence.Query;

import org.jboss.seam.Component;

import es.rbcdexiais.boleta.entity.OrderType;


public class OrderTypeConverter implements Converter {
   
   EntityManager em;

    public Object getAsObject(FacesContext facesContext, UIComponent
            component,
            String string)  {

        if (string == null) {
            return null;
        }

        EntityManager em= (EntityManager)Component.getInstance("entityManager");  
        OrderType orderType=null;
        try{
            Query query = em.createQuery("select orderType From OrderType orderType where orderType.typeCode=:typeCode");
            query.setParameter("typeCode", string);
            orderType = (OrderType)query.getSingleResult();
        }catch(Exception e)
        {
             e.printStackTrace();
        }
        return orderType;
    }
   
    public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) {
        String ret = "";
        if ((arg2 != null) && (arg2 instanceof OrderType)) {
            ret =  ((OrderType)arg2).getTypeCode() +"";
        }
        return ret;
        
    }
 }

In my case typeCode is the primary key of OrderType.
good luck!

I forgot to explain that in a converter you always must implement these two methods:
-getAsObject
-getAsString

This is because you are implementing Converter interface.
In this link you may find converter API for more information about converters.

hi karunakaran, did it work?
