I am using Netbeans Ide to populate a JFRame with some JLabels.
I added three JLabels with corresponding JTextFields . I can correctly see all the three JLabels at desing time, but one of them, the last one added, disappears at run time.
I checked the JLabels properties and they are 100% identical.
Folowing is the InitComponents() code generated by the Ide (the JLabel that doesn't appear is the JLabel4):

  jLabel1 = new javax.swing.JLabel();

    jTextField1 = new javax.swing.JTextField();

    jLabel2 = new javax.swing.JLabel();

    jTextField2 = new javax.swing.JTextField();

    jLabel3 = new javax.swing.JLabel();

    jScrollPane1 = new javax.swing.JScrollPane();

    jList1 = new javax.swing.JList();

    jTextField3 = new javax.swing.JTextField();

    jLabel4 = new javax.swing.JLabel();



    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    setName("jFrameCreateNet"); // NOI18N



    org.jdesktop.application.ResourceMap resourceMap = org.jdesktop.application.Application.getInstance(mccullochpitts1.McCullochPitts1App.class).getContext().getResourceMap(JFrameCreateNet.class);

    jLabel1.setText(resourceMap.getString("jLabel1.text")); // NOI18N

    jLabel1.setName("jLabel1"); // NOI18N



    jTextField1.setText(resourceMap.getString("jTextFieldNetName.text")); // NOI18N

    jTextField1.setName("jTextFieldNetName"); // NOI18N



    jLabel2.setText(resourceMap.getString("jLabel2.text")); // NOI18N

    jLabel2.setName("jLabel2"); // NOI18N



    jTextField2.setText(resourceMap.getString("jTextFieldNumberOfLayers.text")); // NOI18N

    jTextField2.setName("jTextFieldNumberOfLayers"); // NOI18N

    jTextField2.addKeyListener(new java.awt.event.KeyAdapter() {

        public void keyTyped(java.awt.event.KeyEvent evt) {

            jTextFieldNumberOfLayersKeyTyped(evt);

        }

    });



    jLabel3.setText(resourceMap.getString("jLabel3.text")); // NOI18N

    jLabel3.setName("jLabel3"); // NOI18N



    jScrollPane1.setName("jScrollPane1"); // NOI18N



    jList1.setModel(new javax.swing.AbstractListModel() {

        String[] strings = { "Item 1", "Item 2", "Item 3", "Item 4", "Item 5" };

        public int getSize() { return strings.length; }

        public Object getElementAt(int i) { return strings[i]; }

    });

    jList1.setName("jListLayerNumber"); // NOI18N

    jScrollPane1.setViewportView(jList1);



    jTextField3.setText(resourceMap.getString("jTextField3.text")); // NOI18N

    jTextField3.setName("jTextField3"); // NOI18N



    jLabel4.setText(resourceMap.getString("jLabel4.text")); // NOI18N

    jLabel4.setMaximumSize(new java.awt.Dimension(47, 14));

    jLabel4.setMinimumSize(new java.awt.Dimension(47, 14));

    jLabel4.setName("jLabel4"); // NOI18N

    jLabel4.setPreferredSize(new java.awt.Dimension(47, 14));

Thanks
