Custom event does not work in uninstall sequence

[#1]

In uninstall sequence, i added a custom event to detect silent mode, but it is not invoked when i run uninstall. Please kindly help. Appreciate your help.

i am using the following code from the "help"

TASK

To determine the interface being used:

1. First, you need to get an instance of the UI using the following code:

WizardUI ui = getWizard().getUI();


2. Next, use the Java instanceof operator to check if the UI is an instance of the AWTWizardUI, SwingWizardUI, or ConsoleWizardUI class. If it is not an instance of any of these classes, then the installation is running in silent mode.

if (ui instanceof AWTWizardUI){


System.out.println("running in AWT mode");


}


else if (ui instanceof SwingWizardUI){


System.out.println("running in Swing mode");


}


else if (ui instanceof ConsoleWizardUI) {


System.out.println("running in Console mode");


}


else {


System.out.println("running in Silent mode");


}


3. To compile this code, you need to import classes/packages into your JAVA file so that the compiler will find the classes that are being used. At a minimum, you need to include the following classes and packages:

import com.installshield.wizard.*;


import com.installshield.wizard.awt*;


import com.installshield.wizard.console*;


import com.installshield.wizard.swing.*;

I'm a bit rusty with ISMP, but perhaps try this:

WizardUI ui = event.getUserInterface( ); 
 
if (ui instanceof SwingWizardUI) 
    // setup is running in Swing mode 
else if (ui instanceof ConsoleWizardUI) 
    // setup is running in console mode 
else 
    // setup is running in silent mode

i will try

[#4]

if i put in WizardUI ui = event.getUserInterface();
it will fail the compile saying that "cannot find symbol" on event.

i guess it is because i am having the custom event calling this method and i was using WizardActionContext? The reason of this guess is i can see in help it says
WizardUI ui = getWizard().getUI();

What is your custom event signature?

[#6]

i think no custom event can work in my current uninstall sequence. any idea why?

signature? onExecuting? (i added wizard action then custom event. then in "Event", select the context then select onExecuting...

[#7]

i guess i see what you mean by signature.

for some reason, by default, the name generated upon clicking onExecuting is a name with long string appended.
now i can see it in event browser, and i cannot delete it

Putting aside detecting the UI mode for the moment, is your event called at all during uninstallation? (If you use JOptionPane.showMessageDialog with a message there, does something show up?)

[#9]

tried, i added JOptionPane.showMessageDialog, No, it does not show.

[#10]

is it jvm? or launcher?
