public interface Identity<T extends Serializable> extends Serializable 
{
    void setIdentity(T identity);
    T getIdentity();

    void setVersion(Integer version);
    Integer getVersion();
}

public class AbstractIdentity implements Identity<String>
{
	private static final long serialVersionUID = 0L;

	private String identity;
        private Integer version;

        public String getIdentity()	{return identity; }
	public void setIdentity(String identity)  { this.identity = identity;	}

   	public Integer getVersion() {	return version; }
	public void setVersion(Integer version) {this.version = version; }
}

public class Profile extends AbstractIdentity implements Serializable 
{
	private static final long serialVersionUID = 1627635140089150111L;
	
	private String name;

if I change the following to:
<s:textfield id="station" name="profile.name" value="A4F83374-B474-11DB-BABC-8E4D56D89593"/>

I get no exception.  I only get it with the attribute that is a generic which is Identity.
