SetModal problem with 2 Jdialogs in Jframe

I have problems when I install my first JDialogmodal and the second non-modal.

This is the functionality I'm trying to implement:

  • When you click the "Check Dialog!" Button, a JDialogCustom Dialog Main will open.
  • If you click Yes in the Custom Dialog Main, another JDialognamed Custom Dialog Search will open.
  • If you click "Yes" in the user dialog search, the User Main dialog should appear in front.
  • And I have to choose any JDialog. For example, if I select Custom Search Dialog, another dialog should go backward and vice versa.

The problem I am facing is when I click “yes” in the user’s “Home” dialog box, then “Custom Search by Dialog” is displayed after the main dialog.

This is because I install Custom Dialog Search modeless. If I have this modal dialog, it displays correctly, but after I click Yes, the Custom Dialog Main will not appear in front.

I even tried to set the parent component of CustomDialogSearch as CustomDialog, the behavior is still not correct.

Below is an example of the code I'm testing.

import java.awt.event.ActionListener;  
import javax.swing.JFrame;  
import javax.swing.JButton;  
import java.awt.event.WindowAdapter;  
import java.awt.event.WindowEvent;  
import java.awt.event.ActionEvent;  
import java.awt.Dimension;   

public class TestTheDialog implements ActionListener {  
    JFrame mainFrame = null;  
    JButton myButton = null;  

    public TestTheDialog() {  
        mainFrame = new JFrame("TestTheDialog Tester");  
        mainFrame.addWindowListener(new WindowAdapter() {  
                public void windowClosing(WindowEvent e) {System.exit(0);}  
            });  
        myButton = new JButton("Test the dialog!");  
        myButton.addActionListener(this);  
        mainFrame.setLocationRelativeTo(null);  
        mainFrame.getContentPane().add(myButton);  
        mainFrame.pack();  
        mainFrame.setVisible(true);  
    }  

    public void actionPerformed(ActionEvent e) {  
        if(myButton == e.getSource()) {  
            System.err.println("Opening dialog.");  
            CustomDialog myDialog = new CustomDialog(mainFrame, true, "Custom Dialog Main?");  
            System.err.println("After opening dialog.");  
            if(myDialog.getAnswer()) {  
                System.err.println("The answer stored in CustomDialog is 'true' (i.e. user clicked yes button.)");  
            }  
            else {  
                System.err.println("The answer stored in CustomDialog is 'false' (i.e. user clicked no button.)");  
            }  
        }
