Hi,

I have to show a MessageBox (to signal an error when the app starts) before the window is created (in WorkbenchAdvisor).

When I run app inside Eclipse, no problem bit when I run app as a product, the shell is null and I get an exception (null pointer) because the shell is null.

Solution ?

Thanks

JPL

HI,

I have found the solution :

Shell shell=null;
IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
if (window!=null)
shell=window.getShell();
else
shell=PlatformUI.getWorkbench().getDisplay().getActiveShell();

MessageBox messageBox = new MessageBox(shell, SWT.ICON_WARNING | SWT.OK);
