refreshing a Textfield

We have a textfield we were talking about in a earlier question.
when the dialog first opens that field has not value assigned to it.  Let me show what the dialog looks like.

Project:  [ jtext   ]  [ change button ]

When the dialog is first opened jtext has not value.  But when the user clicks the change button that open another dialog.  It is when the dialog is opening we get the value for jtext.

private void showProjectSelectDialog() {
      EdiSelectProjectDialog ar = new EdiSelectProjectDialog(this, session, appReg);
	  EdiProject newProject = ar.getSelectedProject();
	  if (newProject != null) {
		  currentProject = newProject;
		  curProject = new JTextField(20);
	  else {
		  System.out.println("No Project\n");

Open in new window

The user from the new dialog can select a different project.  The dialog goes away, but I am not sure how to update the jtextfield to show the new value.  Is there a refresh? or some kind of listener?
