Migrating from Netbeans

Hi at all,

I would migrate from netbeans to intellij and during my tests I can't build my sample application. Always I received an "Exception in thread "main" java.lang.NullPointerException"

I've seen that in my code there is createUiComponents that I want to delete but always  I received an error that says that there is a custom component in my form....but there isn't !!!

Can anyone help me??

Thanks

Alex

below my simple code !

import javax.swing.*;

/**

public class testInterfaccia {

    private JPanel panel;

    private JButton button1;

    private JTextArea textArea1;

    private JTextField textField1;

    private JLabel labelTest;

    private JLabel label;

    private JScrollPane myscrollpane;

    public static void main(String[] args) {

        JFrame frame = new JFrame("testInterfaccia");

        frame.setContentPane(new testInterfaccia().panel);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.pack();

        frame.setVisible(true);

    }

    private void createUIComponents() {

        // TODO: place custom component creation code here

    }

}
