Vaadin - Liferay Control Panel

Hi all,

i’m trying to develop a liferay control panel application. So i put in liferay-portlet.xml ( generated by eclipse-vaadin-liferay plugin ). The problem is that option is not valid for this liferay-portlet.xml version.

¿Someone have the same problem?

Thank you!
