folks,

I am struggling to add a multiple upload adds on in my web app. I am using ivy and able to code as shown in "MultiFileUpload" Highlights.

I am getting this error, where I am missing?

Hi!

You appear to be using DefaultWidgetset, when you should be using a custom widgetset that inherits both DefaultWidgetset and the add-on's widgetset. If you are using Vaadin Eclipse plugin just compiling widgetset should create one for you. Otherwise you'll need to create one for yourself and add the annotations or web.xml references yourself. You can read more about compiling widgetsets e.g. here.
