Problem with WidgetSet compilation


I am working with a Vaadin application with IDEA, and I am trying to use a GWT-Bootstrap Widget as outlined here: I have a GWT facet set in IDEA to compile the module, and the GWT compiler reports no error. But when I try to instantiate the VBootstrapButton, this error appears on deployment:

Widgetset ‘com.vaadin.DefaultWidgetSet’ does not contain implementation for com.example.hello.BootstrapButton. Check its component connector’s @Connect mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions.

I’ve attached my class structure.

The *widgetset.gwt.xml file should be in the parent of client, not inside client.

If it doesn’t work after fixing this, try to perform widgetset compilation with the extra parameter “-strict” and check its output.
