java awt or Swing component missing or not shown

Question

i've been charged with a new software tool, and i m trying to test it.

PROBLEM: I noticed a difference between mine GUI and the GUI of the tool run on the server: a component is missing! It is like if it's not shown, because i went in debug mode, and everything seems to be fine. this image shows the different:

different

as you can see, the "Shaft end Dia" component is missing between the others 2 components.

CODE: here is a code part. There are lots of items that get instantiate and added in the same way, but it doesn't apper on my pc (but they works well in others!!)

//PanelContainerClass
public class myInputPanel extends JPanel {
//myInputPanel fields
private JPanel myPanelMissing = null;
private JLabel jLabel_ofPanelMissing = null;

//myInputPanel is added to the mainFrame.
public myInputPanel() {
    super();
    initialize();
}

private void initialize() {
    //a GridBagConstraints is created for each panel i m going to add to myInputPanel
    GridBagConstraints gbc6 = new GridBagConstraints();
    gbc6.gridx = 6;
    gbc6.ipadx = 46;
    gbc6.fill = GridBagConstraints.BOTH;
    gbc6.insets = new Insets(0, 0, 0, 0);
    gbc6.ipady = 0;
    gbc6.gridy = 1;
    //in a similiar way others gbc are instantiate

    //a layout is given to myInputPanel
    GridBagLayout gridBagLayout = new GridBagLayout();
    gridBagLayout.columnWidths = new int[]{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 176, 0, 63, 0, 0, 0, 0, 0, 0, 0};
    this.setLayout(gridBagLayout);
    this.setSize(1185, 120);        
    this.setPreferredSize(new Dimension(1164, 143));
    this.setBorder(BorderFactory.createEtchedBorder(EtchedBorder.LOWERED));


    // add others panels to myInputPanel using this.add(getPanel_X(), gridBagConstraintsN);
    this.add(getmyPanelMissing(), gridBagConstraints6);
    // add others panels to myInputPanel using this.add(getPanel_Y(), gridBagConstraintsM);

}

private JPanel getmyPanelMissing() {
    if (myPanelMissing == null) {
        //in debug it get inside the if
        jLabel_ofPanelMissing = new JLabel();
        jLabel_ofPanelMissing.setHorizontalAlignment(SwingConstants.CENTER);            
        jLabel_ofPanelMissing.setText("<html><body>" +                  
                "<table cellspacing='0';cellpadding='0';> <tr> <td align='center'>Shaft end Dia</td> </tr> <tr> <td align='center'>[mm]</td> </tr></table>" +                           
                "</body></html>");
        GridLayout lay = new GridLayout();
        lay.setRows(1);
        myPanelMissing = new JPanel();
        myPanelMissing.setBorder(new SoftBevelBorder(SoftBevelBorder.RAISED));
        myPanelMissing.setLayout(lay);
        myPanelMissing.add(jLabel_ofPanelMissing, null);
    }
    return myPanelMissing;
}

}

What i tried to do is:

running it via my Eclipse: FAIL
running the jar via .bat file: FAIL (FAIL means it doesn't appear)
running the jar on the server via .bat file: WORKS
running the jar via eclipse on a colleague's computer by downloading the code via cvs: WORKS
running the jar via .bat on colleague's computer giving him my files: WORKS
running the jar via .bat on colleague's computer with files compiled by himself: WORKS
commenting the previous panelColumn on my code: WORKS!!!!

NOTE: 1) java version: 1.7.0.75 (either on mine pc either on my collegue pc) 2) OS: window 7 on Vbox (either me and collegue) 3) Eclipse Luna 4.x (same version again for both)

QUESTION: Has anyone had this kind of problems? Any idea about how to solve it?

Thank you all in advance!

*"Any idea about how to solve it?"* (Probably) fix the code. For better help sooner, post an [MCVE](http://stackoverflow.com/help/mcve) (Minimal Complete Verifiable Example) or [SSCCE](http://www.sscce.org/) (Short, Self Contained, Correct Example). — Andrew Thompson, Feb 23 '15 at 14:30
it cannot be a code problem, otherwise it would give the same problem on server and on my colleague computer but it doesn't. — Robdll, Feb 23 '15 at 14:40
*"it cannot be a code problem"* Famous last words.. *"otherwise it would give the same problem.."* The problems will be random if the core problem is `null` layouts, GUI code not being on the EDT, setting preferred sizes ... — Andrew Thompson, Feb 23 '15 at 14:59
i didn't get what your trying to communicate. But if you want to waste time on a working code, let do it, i m gonna post you the code flow in a row. — Robdll, Feb 23 '15 at 15:08
You still haven't post an `MCVE` or 'SSCCE` so we can't help. — camickr, Feb 23 '15 at 16:18
fortunally you are not the whole community, so, put this "we" where you preffer. I m gonna post a MCVE soon for those who wants to help me out. — Robdll, Feb 23 '15 at 16:26

You must increase the area of the your panel myInputPanel with the method setBounds()

Thank you very much, you found the problem! The father component wasn't big enough to show everything, increasing the size of it has solved the problem! – Robdll Feb 24 '15 at 12:51
See [Should I avoid the use of set(Preferred|Maximum|Minimum)Size methods in Java Swing?](http://stackoverflow.com/q/7229226/418556) (Yes.) That advice applies doubly to `setSize(..)`. – Andrew Thompson Feb 27 '15 at 01:23
