Can I add a ContentPanel into a ContentPanel on a mouse click event in GXT

Question

I want to remove all elements from a ContentPanel on a mouse click event and add new ones. It is working fine with removeAll() method, this removes all existing components. But when I want to add a new Component it is not added.

Maybe something like this i omitted the click handler but you should get the idea from this.

private ContentPanel contentPanel;

public SwapScreen() {
 contentPanel = new ContentPanel();
 add(contentPanel);
}

public void swap1() {

   /*This should be split into a separate
    method and called only once to avoid recreating them.*/
   field1 = new TextField<String>();
   contentPanel.add(field1);

   field2 = new TextField<String>();
   contentPanel.add(field2);

  this.layout(true);
}

public void swap2() {

   /*This should be split into a separate
    method and called only once to avoid recreating them.*/
   anotherField1 = new TextField<String>();
   contentPanel.add(anotherField1);

   anotherField2 = new TextField<String>();
   contentPanel.add(anotherField2);

   this.layout(true);
}

Most important part is this.layout(true) to force it to refresh your layout,
