    Cannot cache an unknown entity in Wiki Example

    Matt Hansen Newbie

      I am having a mapping error in the default Wiki Example using jboss-seam-2.2.0.GA and jboss-5.1.0.GA.


      Before the error occurs, this line shows up in the output:




      12:33:44,760 INFO  [Ejb3Configuration] found EJB3 Entity bean: org.jboss.seam.wiki.core.preferences.WikiPreferenceValue




      This leads me to believe that the entities are being found, but the reference to them is lost.


      The stacktrace is:
