I get this error page when i insert multiple ‘/’ into URL and/or try to navigate depending on how many ‘/’ are included.
For example when i create a valid url for my vaadin application and insert two (‘//’), the url is resolved, content showed, but then when i try to navigate using UI controls, this error shows up.
Another example might be when i insert multiple (‘/////’) inside url, the error page shows up immediately.
No error logs, just this page, which seems unrelated to flow or spring…
I am using latest flow 24.8.5 and spring 3.5.4 and tomcat container.
I have implemented custom ErrorHandler, but it is not catching this error
@Component
public class VaadinErrorHandler implements ErrorHandler {
@Override
public void error(final ErrorEvent event) {
EbozLogger.w(MessageFormat.format("Uncaught vaadin exception on component [{0}]: {1}",
event.getComponent().isPresent() ? event.getComponent().get().getClass().getSimpleName() : "",
ExceptionUtils.getStackTrace(event.getThrowable())));
val ui = UI.getCurrent();
if (ui != null) {
ui.access(() -> {
showErrorDialog(event.getThrowable(), ui);
ui.push();
});
}
}
