JFrame disaperes after creation.

Hello guys. what am I doing wrong here ?? Im trying to create a
JFrame from a controler class with

 View v = new view(this);

 which should create a View as follows

package sspclient;

import javax.swing.*;
import javax.swing.Icon.*;
import java.awt.*;

/**

public class View extends JFrame{

    private final String[] type = {"P=C5SE","SAX","STEN"};
   // String[] iconAdress = {"Images/paperroundsm.gif","Images/
Scissorsroundsm.gif",
    // "Images/Rockroundsm.gif"};

    Player[] p = new Player[2];
    MFrame[] frames = new MFrame[2];

    public class MFrame extends JPanel{

        JLabel name = new JLabel();
        JTextField msg = new JTextField("msg");
        JPanel buttons = new JPanel();
        JButton[] sSP = new JButton[3];
        JLabel status = new JLabel("Score");
        JTextField score = new JTextField();
    }

    public View(SSPClient ssp){

        p[0] = ssp.p[0]; p[1] = ssp.p[1];

        FlowLayout fLayout = new FlowLayout();
        setLayout(fLayout);

        for (MFrame mF : frames) {

            mF = new MFrame();
            mF.setLayout(new BoxLayout(mF, BoxLayout.PAGE_AXIS));
            mF.add(mF.name);
            mF.add(mF.msg);
            mF.buttons.setLayout(new BoxLayout(mF.buttons,
BoxLayout.LINE_AXIS));
            int i = 0;
            for (JButton jB : mF.sSP) {
                jB = new JButton(type[i]);

                // ImageIcon iI = new ImageIcon();
                //jB.setIcon(iI);
                mF.buttons.add(jB);
                jB.addActionListener(ssp);
                jB.setActionCommand(type[i]);
                i++;
            }
            mF.add(mF.buttons);
            mF.add(mF.status);
            mF.add(mF.score);
            add(mF);
        }

        // frames[1].name.setText("Datorn");
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        pack();
        setVisible(true);
    }

    public void doRefresh(){
    int i = 0;
    for (MFrame mF : frames){
        mF.msg.setText(p[i].moveString);
        mF.score.setText(Integer.toString(p[i].getPoints()));
        i++;
    }

    pack();
    repaint();

    }

}

then when i try to call

v.frames[0].msg.setText("Hello");

I get a nullpointerexception. Now why is that. I just dont get it.
Also if you have any crueteque about my way of coding then that would
be verry verry helpful and thx in advance.
