Creating a Validator
Creating a validator class should be fairly simple. All you need to do is create a class that extends com.ptc.core.ui.validation.DefaultUIComponentValidator.
The class below represents a skeleton for a simple validator class.
package com.ptc.windchill.enterprise.myPackage.validators;
import com.ptc.core.ui.validation.DefaultUIComponentValidator;
public class MyValidator extends DefaultUIComponentValidator{
//override one or more validation methods from
DefaultUIComponentValidator
}
