Hi,

I was not able to reproduce the problem you describe.

Here is what I tried:

import javax.microedition.midlet.*;
import org.eclipse.ercp.swt.mobile.Command;
import org.eclipse.ercp.swt.mobile.ListBox;
import org.eclipse.ercp.swt.mobile.ListBoxItem;

public class Template extends MIDlet implements Runnable {

    private Thread UIThread;
    private Display display;
    private Shell shell;

    public void startApp() {
        if (UIThread == null) {
            UIThread = new Thread(this);
            UIThread.start();
        }
    }

    public void pauseApp() {
    }

    public void destroyApp(boolean unconditional) {
        shell.dispose();
    }

    public void run() {
        display = new Display();
        shell = new MobileShell(display, 0, MobileShell.SMALL_STATUS_PANE);
        shell.setText("MobileShell");
        shell.setLayout(new FillLayout(SWT.VERTICAL));
        
        final ListBox list = new ListBox(shell, SWT.V_SCROLL, ListBox.LB_STYLE_2LINE_ITEM);
        ListBoxItem[] items = new ListBoxItem[100];
        for (int i = 0; i < items.length; i++) {
            items[i] = new ListBoxItem(i + " item", null, i + " item", null);
        }
        list.setDataModel(items);
        
        list.addSelectionListener(new SelectionListener(){
            public void widgetDefaultSelected(SelectionEvent arg0) {
                list.removeSelectionListener(this);
                
                Shell s = new Shell(shell);
                s.open();
                
                TimedMessageBox dlg = new TimedMessageBox(shell, SWT.ICON_WORKING);
                dlg.setMessage("Please wait");
                dlg.open();
            }
            public void widgetSelected(SelectionEvent arg0) {
            }});
        
        Command cmd = new Command(shell, Command.EXIT, 0);
        cmd.setText("Exit");
        cmd.addSelectionListener(new SelectionListener(){
            public void widgetDefaultSelected(SelectionEvent arg0) {
            }
            public void widgetSelected(SelectionEvent arg0) {
                shell.dispose();
            }});
        
        shell.layout();
        shell.open();

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }

        display.dispose();
        notifyDestroyed();
    }

first of thank you Petru.Motrescu for your reply

OK i will try to describe problem with simple scenario

step by step:
i think you get my point is that i use ListBox and using its selectionlistner method

i open other shell when i click on the item of ListBox (i have see your code , i think you get my point)

now i am testing application in Nokia N97 Device ok
when user click on ListBox (you and me both are showing TimedMessageBox) item at the same time if suddenly i changing mobile screen orientation until the new shell is not opening ---in you code this line "s.open();" is not still executing--(in Nokia N97 Device -i change portrait to Landscape or Landscape to portrait mode) at the same time my application is going directly to crash without any message or alert

now i think you get my point sir,


thank you
