Update methode in model-view-controller-pattern doesn't work!

Question

I'm writing a program in Java which contains several classes. It must be possible to produce an array random which contains Human-objects and the Humans all have a date. In the program it must be possible to set the length of the array (the number of humans to be produced) and the age of the humans. In Dutch you can see this where is written: Aantal mensen (amount of humans) and 'Maximum leeftijd' (Maximum age). Here you can find an image of the graphical user interface: http://1.bp.blogspot.com/_-b63cYMGvdM/SUb2Y62xRWI/AAAAAAAAB1A/05RLjfzUMXI/s1600-h/straightselectiondemo.JPG
The problem I get is that use the model-view-controller-pattern. So I have a model which contains several methodes and this is written in a class which inherits form Observable. One methode is observed and this method is called 'produceerRandomArray()' (This means: produce random array). This method contains the following code:
public void produceerMensArray() throws NegativeValueException{
     this.modelmens = Mens.getRandomMensen(this.getAantalMensen(), this.getOuderdom());
for (int i = 0; i < this.modelmens.length; i++) {
          System.out.println(this.modelmens.toString());
this.setChanged();
this.notifyObservers();
Notice the methods setChanged() and notifyObservers. In the MVC-patterns, these methods are used because they keep an eye on what's happening in this class. If this method is called, the Observers will notice it.
So I have a button with the text 'Genereer' as you can see on the image. If you click on the button it should generate at random an array. I wrote a controller with the following code:
package kristofvanhooymissen.sorteren;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
/**Klasse GenereerListener.
* @author Kristof Van Hooymissen
public class GenereerController implements ActionListener {
     protected StraightSelectionModel model;
     /**Constructor.
     *@param model Een instantie van het model wordt aan de constructor meegegeven.
     public GenereerController(StraightSelectionModel model) {
          this.model = model;
     /**Methode uit de interface ActionListener.
     * Bevat code om de toepassing te sluiten.
     public void actionPerformed(ActionEvent arg0) {
     this.model=new StraightSelectionModel();
     try{
     this.model.produceerMensArray();
     } catch (NegativeValueException e){
          System.out.println("U gaf een negatieve waarde in!");
     this.model.setAantalMensen((Integer)NumberSpinnerPanel.mensen.getValue());
     this.model.setOuderdom((Integer)NumberSpinnerPanel.leeftijd.getValue());
StraighSelectionModel is of course my model class. Nevermind the methods setAantalMensen and setOuderdom. They are used to set the length of the array of human-objects and their age.
Okay. If I click the button my observers will notice it because of the setChanged and notifyObservers-methods. An update-methode in a class which implements Observer.
This method contains the follow code:
public void update(Observable arg0,Object arg1){
          System.out.println("Update-methode");
          Mens[] temp=this.model.getMensArray();
          for (int i = 0; i < temp.length; i++) {
               OnbehandeldeLijst.setTextArea(temp[i].toString()+"\n");
This method should get the method out of the model-class, because the produceerRandomArray()-methode which has been called by clicking on the button will save the produce array in the model-class. The method getMensArray will put it back here in the object named temp which is an array of Mens-objects (Human-objects). Then aftwards the array should be put in the textarea of the unsorted list as you could see left on the screen on the image.
Notice that in the beginning of this method there is a System.out.println-command to print to the screen as a test that the update-method has been called.
The problem is that this update method won't work. My Observable class should notice that something happened with the setChanged() and notifyObservers()-methods, and after this the update class in the classes which implement Observer should me executed. But nothing happenens. My controllers works, the method in the model (produceerRandomArray() -- produce random array) has been executed, but my update-method won't work.
Does anyone has an explanation for this? I have to get this done for my exam an the 5th of january, so everything that could help me would be nice.
Thanks a lot,
Kristo

This was driving me nuts, I put in a larger SSD today going from a 120GB to a 240GB and blew away my Windows Partition to make the process easier to expand OS X, etc.  After installing windows again the only thing in device manager that wouldn't load was the Bluetooh USB Host Controller.  Tried every package in Bootcamp for version 4.0.4033 and 5.0.5033 and no luck.
Finally came across this site:
http://ron.dotsch.org/2011/11/how-to-get-bluetooth-to-work-in-parallels-windows- 7-64-bit-and-os-x-10-7-lion/
1) Basically Right click the Device in Device manager, Go to Properties, Select Details tab, Choose Hardware ids from Property Drop down.   Copy the shortest Value, his was USB\VID_05AC&PID_8218 
2) Find your bootcamp drivers and under bootcamp/drivers/apple/x64 copy AppleBluetoothInstaller64 to a folder on your desktop and unzip it.  I use winrar to Extract to the same folder.
3) Find the files that got extracted/unzipped and open the file with notepad called AppleBT64.inf
4) Look for the following lines:
; for Windows 7 only
[Apple.NTamd64.6.1]
; No action
; OS will load in-box driver.
Get rid of the last two lines the following:
; No action
; OS will load in-box driver.
And add this line, paste your numbers in you got earlier for USB\VID_05ac&PID_8218:
Apple Built-in Bluetooth=AppleBt, USB\VID_05ac&PID_8218
So in the end it should look like the following:
; for Windows 7 only
[Apple.NTamd64.6.1]
Apple Built-in Bluetooth=AppleBt, USB\VID_05ac&PID_8218
5) Save the changes
6) Select Update the driver for the Bluetooth device in device manager and point it to the folder with the extracted/unzipped files and it should install the Bluetooth drivers then.

Just found this link as well that does the same thing:
