Architecture Problem (validation)
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?!
