I’m implementing a Vaadin portlet to be used in Liferay. The portlet needs to monitor some services and display the status of those services. It needs to refresh its view every X seconds (where X is user configurable from inside the portlet UI.)
Is there a way to have Vaadin add some javascript timer on the client side that trigger some events on the application/server side?
Just to note that server push is still not available for portals but is something we’d like to get to work soon. Thus, the built-in refresh mechanism is currently the best way to go with Vaadin 7.
