The demo @ http://vaadin.com/directory#addon/visualizationsforvaadin
is no longer working.
Thanks
The server hosting the virtual machine with the demo was shut down recently for some power infrastructure maintenance. Apparently, Tomcat has not been configured to start up automatically on this virtual machine when the server comes up.
Phil should be able to start it, and probably also configure it to start automatically.
The demo on http://vaadin.com/directory#addon/visualizationsforvaadinis doesn’t work again.
Please, could you restart the server?
Thanks.
Up and running again! Thanks for reporting.
