Description

On the latest snapshot of TomEE 2, switching out MyFaces for Mojarra 2.2.10, you get a NullPointerException when trying to navigate into a JSF flow. I'm using the example here: http://www.byteslounge.com/tutorials/jsf-flow-example with the required change of making OrderBean passivatible by having it implement Serializable.

This is the stack trace:
