New to Java

Hi Guys,

I am trying to set the string to a JTextField with the filepath that the JFileChooser collects from the user. My testing shows that the filepath is collected correctly, and in further investigating I believe that I have a concurrency problem.
So I have tried to put the setText() method away from the EDT and it's still not working. Can you please have a look and let me know how I can get the setText() method actually setting the text?

Thank you, and let me know if need to look at the other JDialogs, JFrames, JFileChooser classes etc.
