title: Netbeans JCalendar Panel
body: <p>This code inside a JFrame form created in netbeans works fine as i'm trying to put a JCalendar in a panel that i create manually.</p>
  
  <pre><code>JCalendar myCalendar =new JCalendar();
  JPanel customPanel = new JPanel();
  customPanel.setSize(400, 250);
  customPanel.setBorder(new LineBorder(Color.BLACK));
  customPanel.add(myCalendar);
  this.add(customPanel);
  </code></pre>
  
  <p>However if i create a panel in netbeans with the help of visual gui builder(matisse)
  and then use this code </p>
  
  <pre><code>JCalendar calendar2 =new JCalendar();
  netbeansPanel.setSize(400, 250);
  netbeansPanel.add(calendar2);
  </code></pre>
  
  <p>the JCalendar is not visible>Any ideas?<br>
