Adding to GridBagLayout

[splen]

Hello community,
got a problem with adding my Components via GridBagLayout.
If I create a new JButton while adding it to the container everything works fine. If I initialize a global JButton field before, then try to add it to the container, it will not work. Im very confused because i cannot see a difference between this methods.

DOES NOT WORK

JLabel lblHeadline;
(...)
lblHeadline= new JLabel(title);
add(lblHeadline, c);

WORKS

add(new JLabel(title), c);

Here is where the problem exactly appears in my classes.

public class SpieltagGUI extends JFrame	{

	private Client cl;
	private Spielplan plan;
	private Tabellenplatz[] platzierungen;
	private String teamName;
	public [B]JLabel lblHeadline[/B], lblStatus, lblPaarung, lblWürfel;
        (...)
	

	public SpieltagGUI(Spielplan plan, Tabellenplatz[] platzierungen, String teamName, Client cl) {
		super();
		String title="Spieltag "+plan.n+" : "+teamName;
		setTitle(title);
		this.cl=cl;
		this.plan=plan;
		this.platzierungen=platzierungen;
		this.teamName=teamName;
		
		setLayout(new GridBagLayout());
		MyGridBagConstraints c= new MyGridBagConstraints();
	
		// LABELS
		[B]lblHeadline= new JLabel(title);[/B]
		c.setValues(0, 0, 3, 1, 1.00, 1.00, 3);
		[B]add(lblHeadline, c);[/B]
           (...)

public class MyGridBagConstraints extends GridBagConstraints {

	public void setValues( 
			int x, int y, 
            int width, int height, 
            double weightx, double weighty, int vfill ) 
	{ 
		switch (vfill) {
                case 0: this.fill = GridBagConstraints.NONE; break;
		case 1: this.fill = GridBagConstraints.HORIZONTAL; break;
		case 2: this.fill = GridBagConstraints.VERTICAL; break;
		default: this.fill= GridBagConstraints.BOTH; break;
		}
		
		this.gridx = x; this.gridy = y; 
		this.gridwidth = width; this.gridheight = height; 
		this.weightx = weightx; this.weighty = weighty; 
	} 
}

Sorry for maybe not the best english.
Thanks for any advices!

To get better help sooner, post a SSCCE (Short, Self Contained, Compilable and Executable) example that demonstrates your problem. not all your code, but not uncompilable snippets either.

When i try the same thing in a small GUI-Testclass, it works fine.
Thought maybe in the code posted, there is a strange mistake anywhere.

My whole project is too huge for posting. Even this small piece of code was shortened to be
logical to you. If you dont see why it shouldn't work in here, its okay.

Thanks for your info anyways!
