Struts 2 Continuations Giving Null Pointer

[reedmd]

I am trying to set up a project using struts 2 and continuations. I can start the application in weblogic with no errors however, when I attempt to access a page I get the following error:

Root cause of ServletException.
java.lang.NullPointerException
at org.apache.struts2.continuations.ContinuationsActionEventListener.pre

Does anyone know what this means? I've been trying forever now and haven't made the slightest bit of headway
