[jboss-user] [JBoss Seam] - Architecture Problem (validation)

[Eethyo]

Hi,
I have a problem with the Validation.

Validator:
package com.ccm30.validators;
  | 
  | import java.util.List;
  | 
  | import javax.persistence.NoResultException;
  | 
  | import org.hibernate.mapping.Property;
  | import org.hibernate.validator.PropertyConstraint;
  | import org.hibernate.validator.Validator;
  | import org.jboss.seam.Component;
  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.framework.EntityController;
  | 
  | import com.ccms30.entities.CcmsProductline;
  | import com.ccms30.entities.CcmsProductlineController;
  | 
  | @Name("myProductlineListValidator")
  | public class MyProductlineListValidator extends EntityController implements
  | 		Validator<MyProductlineList>, PropertyConstraint  {
  | 
  | 
  | 	
  | 	// part of the Validator<Annotation> contract,
  | 	// allows to get and use the annotation values
  | 	public void initialize(MyProductlineList parameters) {
  | 
  | 	}
  | 
  | 	// part of the property constraint contract
  | 	public boolean isValid(Object value) {
  | 		
  | 		if (value == null){
  | 			System.out.println("Value is null");
  | 			return true;
  | 		}
  | 			
  | 		if (!(value instanceof String))
  | 		{
  | 			System.out.println("Value is not a string");
  | 			return false;
  | 		}
  | 			
  | 		String string = (String) value;
  | 		String trimmed = string.trim();
  | 		
  | 		try{
  | 			CcmsProductline cpl = (CcmsProductline) createQuery(
  | 			"select cpl from CcmsProductline cpl where cpl.name=:name")
  | 			.setParameter("name", trimmed).getSingleResult();
  | 
  | 			System.out.println("Value is in List");
  | 			return true;
  | 		}catch(NoResultException e)
  | 		{
  | 			System.out.println("Value is not in List");
  | 			return false;
  | 		}
  | 
  | 	}
  | 
  | 	public void apply(Property arg0) {
  | 
  | 	}
  | 
  | }
  |

I always get a "Stackoverflow" Exception.

I think i know why, because my Productline i get wants to validate its value and so on. how to avoid this?
Where should I set my validator?

Can you help me?!
