What is the reason for this umbrella exception

The application loads in the browser, however it throws exceptions that say

11: 59: 49.770 [ERROR] [loginform] Unclosed exception com.google.gwt.event.shared.UmbrellaException: one or more exceptions were caught, see the full set in UmbrellaException # getCauses at com.google.gwt.event.shared. HandlerManager.fireEvent (HandlerManager.java:129) at com.google.gwt.user.client.ui.Widget.fireEvent (Widget.java:129) at com.google.gwt.event.dom.client.DomEvent.fireNativeEvent ( DomEvent.java:116) on com.google.gwt.user.client.ui.Widget.onBrowserEvent (Widget.java:177) on com.google.gwt.user.client.DOM.dispatchEventImpl (DOM.java:1351)

What is the reason and how to solve it?

You are missing the interesting part. Create an exception handler, as in this question . update:

As you can see here: GWT / JAVA Throw exception removed

The stack should be longer. There is a main reason related to Umbrella-Exception.

Try to resolve errors that occurred in your application. I already answered the same question GWT client umbrellaexception to get the full error message in java

I'm from the future) I had the same problem today. I just foggot to add a .js folder in the project and a few lines of code to the file. Yourmodule.html. See the Installation Guide here: http://www.moxiegroup.com/moxieapps/gwt-highcharts/userguide.jsp#installation
