Get started

This add-on allows to add a sub-window to inform that an error was caused by an exception.

Default presentation
Default presentation

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 dialog (ErrorWindow) can be automatically invoked through an error handler configured by com.flowingcode.vaadin.addons.errorwindow.VaadinServiceInitListenerImpl or just by itself calling ErrorManager.showError(). It is also possible to use the ErrorWindow directly for messages customization purposes.
