Thread: Swing JLayer doesn't handle my AWTEvent

Hello everyone, I have an issue I posted in "What's wrong with my code" section.

I working on an assignment. My Swing application should display errors that may occur as a pop-up (not a separate new window, by a smooth pop-up). I wanted to use JLayer eventDispatched() method for that.

I have created my

package event;
 
import java.awt.*;
import java.awt.event.*;
 
import javax.swing.*;
 
public class ErrorEvent extends ActionEvent{
 
	public static final long ERROR_MASK = MouseEvent.MOUSE_EVENT_MASK;
	public static final int ID = 2006;
 
	public ErrorEvent(Object source) {
		super(source, ID, "errorCommand");
		//I HAVE TRIED LIKE THIS:
		((JComponent) source).dispatchEvent(this);
	}
 
	 public void fire() {
		 	//AND LIKE THIS:
	        Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(this);
 
	        //THIS LINE SHOWS THAT EVENT IS ACTUALLY BEING POSTED:
	        System.out.println(Toolkit.getDefaultToolkit().getSystemEventQueue().peekEvent(2006));
	        this.consume();
	 }
}

I have picked MOUSE_EVENT_MASK to track if eventDispatched() handles any events at all (in fact, it does seem to be able to Listen to mouse events).

Here is code for JLayer:

JLayer<JComponent> layer = new JLayer<JComponent>(loginPanel, new LayerUI<JComponent>() {
 
			@Override
			public void installUI(JComponent c) {
				super.installUI(c);
				JLayer<JComponent> layer = (JLayer<JComponent>)c;
				layer.setLayerEventMask(ErrorEvent.ERROR_MASK);
			}
 
			@Override
			public void uninstallUI(JComponent c) {
				super.uninstallUI(c);
				JLayer<JComponent> layer = (JLayer<JComponent>)c;
				layer.setLayerEventMask(0);
			}
 
 
			@Override
			public void eventDispatched(AWTEvent e, JLayer<? extends JComponent> l) {
				System.out.println(e);
			}
}

For some reason no matter how I try to dispatch my event (any event for that matter), they are not being handled by JLayer:

layer.dispatchEvent(new ErrorEvent(layer));
ErrorEvent errorEvent = new ErrorEvent(loginPanel);
errorEvent.fire();

Please help, I have been trying to solve this issue for 5 hours now and nothing seems to help
