Hi Samuel.

Thanks for your help.

This is the code of the entity OrderItems:

package org.domain.OrderEntry.entity;

// Generated 28/08/2008 10:46:25 by Hibernate Tools 3.2.2.GA

import javax.persistence.Column;

@Entity
@Table(name = "orderitem", catalog = "test")
public class Orderitem implements java.io.Serializable {

        private Integer orderItemId;
        private Serviceorder serviceorder;
        private String itemDescription;

        public Orderitem() {
        }

        public Orderitem(Serviceorder serviceorder, String itemDescription) {
                this.serviceorder = serviceorder;
                this.itemDescription = itemDescription;
        }

        @Id
        @GeneratedValue(strategy = IDENTITY)
        @Column(name = "OrderItemID", unique = true, nullable = false)
        public Integer getOrderItemId() {
                return this.orderItemId;
        }

        public void setOrderItemId(Integer orderItemId) {
                this.orderItemId = orderItemId;
        }

        @ManyToOne(fetch = FetchType.LAZY)
        @JoinColumn(name = "OrderID", nullable = false)
        @NotNull
        public Serviceorder getServiceorder() {
                return this.serviceorder;
        }

        public void setServiceorder(Serviceorder serviceorder) {
                this.serviceorder = serviceorder;
        }

        @Column(name = "ItemDescription", nullable = false, length = 45)
        @NotNull
        @Length(max = 45)
        public String getItemDescription() {
                return this.itemDescription;
        }

        public void setItemDescription(String itemDescription) {
                this.itemDescription = itemDescription;
        }

}

and this is the code of the OrderItemHome:

package org.domain.OrderEntry.session;

import org.domain.OrderEntry.entity.*;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.framework.EntityHome;

@Name("orderitemHome")
public class OrderitemHome extends EntityHome<Orderitem> {

        @In(create = true)
        ServiceorderHome serviceorderHome;

        public void setOrderitemOrderItemId(Integer id) {
                setId(id);
        }

        public Integer getOrderitemOrderItemId() {
                return (Integer) getId();
        }

        @Override
        protected Orderitem createInstance() {
                Orderitem orderitem = new Orderitem();
                return orderitem;
        }

        public void wire() {
                getInstance();
                Serviceorder serviceorder = serviceorderHome.getDefinedInstance();
                if (serviceorder != null) {
                        getInstance().setServiceorder(serviceorder);
                }
        }

        public boolean isWired() {
                if (getInstance().getServiceorder() == null)
                        return false;
                return true;
        }

        public Orderitem getDefinedInstance() {
                return isIdDefined() ? getInstance() : null;
        }

}


The page.xml for the OrderItemEdit.xhtml is:
