Hi everyOne

My problem is like below:
I have a modal dialog box extends form JDialog, When the user fill field and clic on OK button I want
1- add a progress bar to indicate file uploading
2- add field to DB
I add this code to the Ok button but nothing happen

  
public void onOkButtonEvent() {
	new Thread() {
	    @Override
	    public void run() {
		SwingUtilities.invokeLater(new Runnable() {
		    public void run() {
			a3DObjectPropertiesDialog.getA3DValidationButtonsPanel().addComponentInFirstPosition(
				a3DObjectPropertiesDialog.getProgressBar(), true);
			a3DObjectPropertiesDialog.getA3DValidationButtonsPanel().validate();
			a3DObjectPropertiesDialog.getA3DValidationButtonsPanel().repaint();
			a3DObjectPropertiesDialog.manageOkButtonClic(); // add fields to DB
		    }
		});
	    }

	}.start();

    }

  

thanks in advance and any help is appreciated
