I am evaluating Vaadin as web framework for portal server (liferay) and had build a few porlets using Vaadin6. I have upgraded the software stack (eclipse/liferay/vaadin) to the latest version vaadin 7.0.7 and have serious problems with my portlets. Classes/interfaces have been deprecated and no clear alternative are provided in the doc.
vaadin6:
public class MyApplication extends Application implements PortletListener, PortletRequestListener
vaadin7:
public class MyApplication extends UI implements PortletListener
or ??
public class MyApplication extends VaadinPortlet
or ??
…
It seems that the handleXXXRequest methods are not properly called ??
Does anybody have working Porlet 2.0 - vaadin 7 code working that he can share ? I understood that the portlet doc will be reworked but for the time being it is very hard to figure out how to migrate the porlets to vaadin 7.
