Need Help with Null Pointer Exception!!!

Hi,

I'm using luxor for UI development. While generating the UI for textfield,
I'm getting Null Pointer exception. Can anyone figure it for me.

The respective codes are

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+++++++++++++++++++++++++++++++++++++++++++++
Test.xul
+++++++++
<xul>
<hbox id="test">
  <vbox>
   <hbox>
      <textfield id="display1" data="value1" enabled="false"/>
   </hbox>
   <hbox>
      <textfield id="display2" data="value2" enabled="false"/>
   </hbox>
   <hbox>
     <button label="swap" command="show" style="width: 100px"/>
   </hbox>
  </vbox>
  </hbox>
</xul>

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
++++++++++++++++++++++++++++++++++++++++++++
TestForm.java
+++++++++++++
package org.luxor.test;
import javax.swing.JTextField;
import luxor.XulForm;
import luxor.XulInput;

public class TestForm extends XulForm {
	XulInput _display1;
	XulInput _display2;

	public TestForm() {
		super("test");
		setup();
	}

	public void init() {

		_display1 = new XulInput(this, "display1");
		_display2 = new XulInput(this, "display2");
		 new ClickBtn(this,"swap");
	}

	public void postInit() {
		System.out.println(_display1);
		System.out.println(_display2);
		JTextField jdisplay1 = (JTextField) _display1.getJComponent();
		jdisplay1.setHorizontalAlignment(JTextField.RIGHT);
		JTextField jdisplay2 = (JTextField) _display2.getJComponent();
		jdisplay2.setHorizontalAlignment(JTextField.RIGHT);
    }

	public void setValue() {
		String value;
		value=_display1.getText();
		_display2.setText(value);
	}
}

Here when i'm doing JTextField jdisplay1 = (JTextField)
_display1.getJComponent();
the _display.getJComponent() is returning null.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+++++++++++++++++++++++++++++++++++++++++++++++++

Can anyone figure out the error for me.

Regards
Ajay
