I created class NewProject extends JInternalFrame. Then I create New...Action named "NEW", localised in File menu. I put code NewProject p = new NewProject(); p.setVisible(true); to the ActionPerformed method of the action.

But when I run the module and click "NEW" in file menu, nothing appears. Where can be problem?
