Introduction In my last blog post, I closed with the following: If you have the Vaadin 7 Control Panel installed and you've deployed the LazyPagedContainer Add On, you can download and deploy the vaadin-sample-portlet-1.0-SNAPSHOT.war file directly from this blog. This is not completely correct.  The Vaadin 7 Control Panel includes...

Introduction So Vaadin provides a core set of widgets, standard widgets that you'd find in any web framework such as radio buttons, buttons, links and text input fields. But like most other frameworks, we as developers want a richer toolset of widgets that go beyond the standard set, usually to encapsulate some bit of a control which is obviously self contained. While...

Liferay ships with a pretty old copy of Vaadin 6, but most documentation and examples out now are for Vaadin 7.  It's pretty easy to upgrade the shared Vaadin environment to Vaadin 7, as simple as installing the Vaadin 7 Control Panel from the Marketplace. When the Vaadin 7 Control Panel is installed, it will purge Vaadin 6 from the Liferay environment and copy an initial...

I published it on Github under my employer's organization (Uppsala University).  The code is really written as a proof of concept,...
