vaadin seam integration

I am having problems running seam and vaadin together and keep getting no event context exception. I think it is more seam related though but maybe somebody found solution to this.

I tried the solution that somebody posted on this forum some time ago ( ) but it does not work for me at all. I can;t even get acces to the seam componenets like Manager or Contexts. While when I use <web:context-filter > in componenets.xml at least I can use them but get the above exception when I for example try to use entitymanager or anything like that.
