Rules Source

[ulil]

I've make rules for input validation :

public class TextValidation implements RulesProvider 
{
 private RulesSource rulesSource;

  public TextValidation()
  {
        DefaultRulesSource rulesSource = new DefaultRulesSource();
        rulesSource.addRules(getRules());
        this.rulesSource = rulesSource;
        
  }
  
  protected Rules getRules() 
  {
        Rules rules = Rules.createRules(getClass());
        Constraints c = Constraints.instance();
        rules.add("inputString", c.all(new Constraint[] { c.required(),  
             c.maxLength(8) }));
        return rules;
  }
  
  public PropertyConstraint getRules(String property) 
  {
       return rulesSource.getRules(getClass(), property);
  }

}

The form :

public class Text extends JFrame implements ActionListener 
{
    private JTextField textUserID = new JTextField();
    private JPasswordField password = new JPasswordField();
    private JButton ok = new JButton("Ok");
    private JButton cancel = new JButton("Cancel");
    private TextValidation validation = new TextValidation();
    
    public Text()
    {
        ok.addActionListener(this);
        FormLayout layout = new FormLayout("r:50dlu,3dlu,80dlu","");
        DefaultFormBuilder builder = new DefaultFormBuilder(layout);
        builder.setDefaultDialogBorder();
        
        builder.append("User ID", textUserID);
        builder.nextLine();
        builder.append("Password",password);
        builder.nextLine();
        builder.append(ButtonBarFactory.buildRightAlignedBar  
             (ok,cancel),3);
        getContentPane().add(builder.getPanel());
        pack();
        show();
  }
  
    public static void main(String args[])
    {
          Text text = new Text();
    }

  public void actionPerformed(ActionEvent e)
  {
      String s = e.getActionCommand();
      if(s.equals("Ok"))
      {
               //here i want to validate value of user ID (textUserID)
      }
  }
}

How I can register my textUserID ?

Thx before

You need to use a Form implementation to use the validation. You have two options:
1. provide an application wide RulesSource
2. make your form model object implement RulesProvider

More info on validation: http://opensource.atlassian.com/conf...rms-Validation

When you want to work without a form (as you show in your code), you will have to register the appropriate listeners to your input fields, and call the validation framework from their methods.
