Hello I'm trying to write a custom validator for my demo app.
I have this class:
/*
* DuplicateValidator.java
*
* Created on February 20, 2007, 1:24 PM
*
* To change this template, choose Tools | Template Manager
* and open the template in the editor.
*/
package org.jfly.demo.edittable.validators;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import org.apache.tapestry.form.IFormComponent;
import org.apache.tapestry.form.ValidationMessages;
import org.apache.tapestry.form.validator.BaseValidator;
import org.apache.tapestry.valid.ValidationConstraint;
import org.apache.tapestry.valid.ValidatorException;
import org.jfly.demo.edittable.vo.Person;
/**
*
* @author kiuma
*/
public class DuplicateValidator extends BaseValidator {
public static final String DUPLICATE_PERSON = "duplicate.person";
public DuplicateValidator() {
}
public DuplicateValidator(String initializer)
{
super(initializer);
}
/**
* Does comparison based on the [EMAIL PROTECTED] Number#doubleValue()}.
*/
public void validate(IFormComponent field, ValidationMessages messages,
Object object)
throws ValidatorException {
List value = (List) object;
List parsedPrs = new ArrayList();
Iterator iter = value.iterator();
Person dupPerson = null;
while (iter.hasNext()) {
Person person = (Person)iter.next();
if (parsedPrs.contains(person)) {
dupPerson = person;
break;
} else {
parsedPrs.add(person);
}
}
if (dupPerson != null)
throw new ValidatorException(buildMessage(messages, field,
dupPerson));
}
private String buildMessage(ValidationMessages messages, IFormComponent
field, Person person)
{
return messages.formatValidationMessage(
getMessage(),
DUPLICATE_PERSON,
new Object[]
{ person.getSurname(), person.getName() });
}
}
--------------------------------------------------------------------------------------
then in hivemodule.xml I have this:
<contribution configuration-id="tapestry.form.validator.Validators">
<validator name="PersonDup" class="
org.jfly.demo.edittable.validators.DuplicateValidator"/>
</contribution>
----------------------------------------------------------------------------------------
The interested Component binding is:
<binding name="validators" value="validators:PersonDup"></binding>
The problem is that when I try to render the page I've this message back:
Validator 'name' must be configured in order to be used. The value is
configured by changing 'name' to 'name=value'.
What am I missing ?
Thx,
kiuma
