Inter Portlet Communication (IPC) is a way of exchange the data between portlets. In Liferay there are different ways we can achieve this. One of them is the client-side IPC that is supported by LIMS MUC. In other words, you may e.g. open a conversation or read user presence from your own portlet. There is only one limitation. Since the communication is client-side LIMS needs to be on...

Introduction So in two previous blogs I introduced Auto Vaadin Add On Deployment and Vaadin 7 Theming.  At the end of the Vaadin 7 Theming blog I said that there was a similar mechanism for handling the deployment of your themes using the Vaadin 7 Control Panel, the mechanism introduced in the Auto Vaadin Add On Deployment blog.

Introduction Vaadin 7 is an active project still in development.  New releases come out regularly with bug fixes (mostly browser compatibility).  New versions come out with new functionality, etc. When using the Vaadin 7 shared environment, the version of Vaadin must be the same across the portal. The reason is the compiled WidgetSets.  When you compile the...

Introduction So the last few Vaadin posts were on some basic introductory stuff, but not a whole lot of fun.  I thought I'd do a blog post on a quick and fun little Vaadin 7 portlet, one that uses HighCharts. So I'm creating a portlet to show a pie chart of registered user ages (based on birthdate).  The fun part about this portlet is that it will use the Liferay API...

It's hard enough to get certain developer types to mingle for even a little while without constantly checking their phones for the best time to make their exit.   It can be challenging to plan a networking event, but for a tech audience, finding the right venue to cultivate great conversation can make the difference between your event hashtag filling up social media and...

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...

Creating the Project ...

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...
