    NullPointerException and No conversation context active

    Andrew Apprentice

      Environment:
      Facelets 1.0.14
      MyFaces 1.1.4 Snapshot
      Seam 1.0.1 GA

      Problem:
      I have having an exception in the RESTORE VIEW of my page. My page flow is this:
      1) User hits a listing page with a data table. User clicks a command link in a row of the table containing a tomahawk updateActionListener.
      2) Action is fired that starts a conversation (@Begin) (this never happens because of the error)
      3) Navigate to the details page

      Here is the exception output:

      I have other pages/beans that are very similar but do not throw this error. I am not sure what is different about this one.

      Any ideas?

      Thanks,
      Andrew
