About the Error Window Add-on for Vaadin 7 category

Error Window Add-on for Vaadin 7: The sub-window shows different information depending on the running mode of the application:

  • if the application is running in debug mode, it shows the stack trace of the exception.
  • if the application is running in production mode, it shows a code to report that can be found in log files.
    The sub-window (ErrorWindow) can be invoke through an error handler (WindowErrorHandler) or just by itself calling the “open” method.
    It is possible to customize the message shown.
    This add-on is a server-side-only component, so there’s no need to recompile the widgetset.
