Hello,
I found that the wizard used for generating a new project template using an 
existing project structure generates a java class file containing a member 

public class XYZPanelVisual extends JPanel implements DocumentListener { ...

private int type;

//which is never referred or used in the class, but redundantly/no effect 
initialized in the generated constructor like: 

public XYZPanelVisual(XYZWizardPanel panel) {
  initComponents();
  this.panel = panel;
  
  //-> 
  this.type = type; 
  //<-
  
  // Register listener on the textFields to make the automatic updates
  projectNameTextField.getDocument().addDocumentListener(this);
  projectLocationTextField.getDocument().addDocumentListener(this);
 }

... 
}

What's the purpose of this variable and the redundant/no effect assignment?

Regards,
Cris
