Problem with JFileChooser when run using Netbeans

Question

I just want to state that I have NO problem writing the code that brings up this component. My problem is what happens when the JFileChooser component is loaded. My environment is Windows Vista, Java SE 1.6.0. -> Netbeans IDE 5.0. The code I use is as follows:
public RegexParser()
JFileChooser openfile = new JFileChooser();
openfile.showOpenDialog(RegexParser.this);
int returnVal = openfile.showOpenDialog(RegexParser.this);
if (returnVal == JFileChooser.APPROVE_OPTION)
//This code gets the path of the file and uses as a parameter to parse data.
filename = openfile.getSelectedFile().getPath();
openfile.setVisible(false);
ParseData(filename);
The problem is when I try to select an option from the combobox labeled "Look In:" Every directory I select which is not the root of the drive will display NO FILES even though there are files in that directory.
Notice: I have also run the same code using the cmd.exe and it works fine. I have also looked at: http://java.sun.com/docs/books/tutorial/uiswing/components/filechooser.html but have found nothing that has helped me.
Can someone explain what is the problem? Is this a known bug in Netbeans? Is there any code that can be used as a workaround?

Answer 1

Yes I copied the code to my machine and run it. The example program had problems when I executed using netbeans it had the problem.
When I executed using Command Prompt there where no problems.
