Porltets in Liferay - Popups open on different computer!!

Hello All,

I am having a very strange behaviour on my vaadin application. I have created 4 different vaadin portlets (2.0) which were deployed to liferay. When I open one portlet on one computer and the same one on another computer the popup windows from the first computer open on the other one! And also the server throws a SessionExpiredException.

Any ideas?

Thank you

I was storing the main window on a static variable and so the second user overode the first user’s window and so all popups of the first user appeared on the second user’s session (push techonology?)…

Thank you
