Hi,

How are you building your project? Which version of IDEA are you using?

I'd suggest to use a Maven build and base your project on our archetype. Then add-ons you declare as a dependency are automatically picked into your application widgetset.

I don't remember excatly how IntelliJ works with non-Maven built project, it might be that you have to update your "ApplicationWidgetset.gwt.xml" file manually to contain the client side extensions from add-ons.

cheers,
matti

Did you create the project using vaadin-archetype-application? What is in you pom.xml? For some reason releavant vaadin jars (vaadin-server.jar) don't appear to be on you classpath.

cheers,

The pom.xml looks good to me, although quite old Vaadin version. You should definitely keep it up to date (today 7.6.6).

I looked you screen capture again and I think I found your error. You seem to have invalid import there. Instead of "import com.vaadin;" there should be "import com.vaadin.ui.UI;".

cheers,
matti

That seems weird. Did you try updating the Vaadin version from pom.xml to 7.6.6 ?
