Java Swing can't add multiple panels to panel

Question

I'm trying to add 2 panels to one panel. Now the problem is, when I add the first or the second one alone, I can see them in the panel. But when I add both off them (put //add(panel2, BorderLayout.SOUTH); out of comment) I don't see any of them. The Weblabel("Test") is always showing. Now both panels have a onclick method and when you can't see them (if they are both added) the onclick still works if you click where the panels are supposed to be.

I already tried other layoutmanagers but without succes. Does anyone know where this problem could be comming from?

setLayout(new BorderLayout());
add(panel1,BorderLayout.NORTH);
add(new WebLabel("Test"), BorderLayout.CENTER);
//add(panel2,BorderLayout.SOUTH);

I initialize both panels in my constructor.

public MultipleFloorPlanEntityPanel(int xCoordinate, int yCoordinate,   FloorPlanEntityPanel panel1, FloorPlanEntityPanel panel2){
    this.xCoordinate = xCoordinate;
    this.yCoordinate = yCoordinate;
    this.panel1 = panel1;
    this.panel2 = panel2;
    layoutComponents();
}

Solved: reinitialized the extra panels and that worked :)

Solution

As you need panel contain two panel? try this

JPanel top = new JPanel(new GridLayout(1,1))
JPanel left = new JPanel();
JPanel right = new JPanel();
top.add(left);
top.add(right);
JFrame frame = new JFrame();
frame.add(top);
frame.setSize(400,400);
frame.setVisible(true);
