Hi,
I have a problem with the Validation.
Validator:

|
| 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?!
