So, i did steps 1 and 2, on no 3 i have an @Out(required = false, scope = ScopeType.SESSION) which should work, but how do I use step 4? I am using a Seam generated project, i can't find anywhere a entityManager, everything is done by Seam. I suppose i have to override a method, but hell if i know which one :(.

Also, now, i tried to deploy with the code i have, i just defined my entityMAnager with this:

<core:filter name="hubFilteredChannels">
  |         <core:name>hubFilteredChannels</core:name>
  |         <core:parameters>
  |             <key>currentHub</key>
  |             <value>#{currentHub}</value>
  |         </core:parameters>
  |     </core:filter>
  | 
  |  <core:managed-persistence-context name="entityManager"
  |                                       auto-create="true"
  |                                       persistence-unit-jndi-name="java:/entityManagerFactory">
  |         <core:filters><value>#{hubFilteredChannels}</value></core:filters>
  |     </core:managed-persistence-context>

And now i get an error when loading the first page:

anonymous wrote : Caused by: org.hibernate.HibernateException: Filter [hubFilteredChannels] parameter [currentHub] value not set

So what is wrong? Why does Seam loads everything on startup??? If I have a bad page I cannot see a thing, the page redirects me to the debug page...
