    <p>Seems like you yourself are doing something wrong, in your code. Without a proper <a href="http://sscce.org/" rel="nofollow noreferrer">SSCCE</a> it's hard to say what thing you doing wrong, since it works perfectly, using same ActionListener for both <code>JMenuItem</code> and <code>JTextField</code>.</p> <p>Here is a sample program to match with yours : </p> <pre><code>import java.awt.*; import java.awt.event.*; import javax.swing.*; public class UpdateLabel { private JLabel label; private String labelText; private ActionListener action = new ActionListener() { public void actionPerformed(ActionEvent ae) { setLabelText((String) ae.getActionCommand()); label.setText(getLabelText()); } }; private void setLabelText(String text) { labelText = text; } private String getLabelText() { return labelText; } private void createAndDisplayGUI() { final JFrame frame = new JFrame("Update Label"); frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); frame.setLocationByPlatform(true); JMenuBar menuBar = new JMenuBar(); JMenu programMenu = new JMenu("Program"); JMenuItem exitMenuItem = new JMenuItem("Exit"); exitMenuItem.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent ae) { frame.dispose(); } }); JMenu labelMenu = new JMenu("Label"); JMenuItem updateMenuItem = new JMenuItem("Update Label"); updateMenuItem.setActionCommand("Updated by JMenuItem"); updateMenuItem.addActionListener(action); programMenu.add(exitMenuItem); labelMenu.add(updateMenuItem); menuBar.add(programMenu); menuBar.add(labelMenu); frame.setJMenuBar(menuBar); JPanel contentPane = new JPanel(); label = new JLabel("I am the LABEL which will be updated!!"); contentPane.add(label); JTextField tfield = new JTextField(10); tfield.setActionCommand("Updated by JTextField"); tfield.addActionListener(action); frame.add(contentPane, BorderLayout.CENTER); frame.add(tfield, BorderLayout.PAGE_END); frame.pack(); frame.setVisible(true); } public static void main(String... args) { SwingUtilities.invokeLater(new Runnable() { public void run() { new UpdateLabel().createAndDisplayGUI(); } }); } } </code></pre> <p>And here is the output in both the cases : </p> <p><img src="https://i.stack.imgur.com/lWtZa.png" alt="Updated with JMenuItem"> and <img src="https://i.stack.imgur.com/8CnZ8.png" alt="Updated with JTextField"></p> <p>Do check out the main method, might be you had failed to put your code inside EDT - Event Dispatcher Thread, that can lead to such issues too. All updates on the Swing GUI, must be done on the Event Dispatcher Thread.</p> <p><strong>LATEST EDIT</strong></p> <p>It seems to me that <code>CreateGalleryXML</code> extends <code>JPanel</code> by the look of it. See at <code>Line 3</code> of this below code taken from your update, here you are initializing a new <code>Object</code> of <code>CreateGalleryXML</code> inside, when you already had one Object <code>window</code> created at <code>Line 1</code>: </p> <pre><code>CreateGalleryXML window = new CreateGalleryXML(); frame.setJMenuBar(window.createMenuBar()); frame.add(new CreateGalleryXML()); </code></pre> <p>So try to change the above thingy to this </p> <pre><code>CreateGalleryXML window = new CreateGalleryXML(); frame.setJMenuBar(window.createMenuBar()); frame.add(window); </code></pre> <p>and see what happens and Please do revert back again :-)</p>

    1. COWow... This did it for me. I pretty much scrapped everything, started with your code, then started building back up from there. I'm still a good bit confused, but I've now gotten far enough along that things are looking like they're going in the right direction. There's enough of the core back in that I can see my message label being updated when necessary. Going back and looking at my previous code, I think it had to do with my createAndShowGUI method was inadvertently creating multiple frames? Maybe?

    2. COI posted my original createAndShowGUI since I think that was the root of all of my problems. That's as an edit to my original post, if you are interested. Thanks again for all of your assistance!!!! I truly appreciate it!

    3. CO@Osh : I had edited my post a bit further, seems like you creating a new Object as mentioned above is the real cause of all problems. Try to rectify that as mentioned above, and Please do revert back :-)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
