Out of sync error google app engine

Hello!

I have big problem with deploying vaadin app to google app engine

Application can be seen here: lifeappinc.appspot.com

In GAE log shows this error:


com.vaadin.terminal.gwt.server.AbstractCommunicationManager handleVariableBurst: Warning: Ignoring variable change for non-existent component, VAR_PID=PID16

Anyone? Would be very thankful if you could help me…

Make sure you are using GAEApplicationServlet

Can you tell me more?

If I put <servlet-class>com.vaadin.terminal.gwt.server.GAEApplicationServlet</servlet-class> into my web.xml file I get error!

Can you tell me more?

Thank you!

That’s what you should use when deploying to GAE. See
http://vaadin.com/wiki/-/wiki/Main/Google AppEngine HOWTO
for more info.

Yes, this is exactly how i did it. But I’m still getting error.

Help wanted!
