DataRow Hessian serialization doesn't work
------------------------------------------

         Key: CAY-571
         URL: http://issues.apache.org/cayenne/browse/CAY-571
     Project: Cayenne
        Type: Bug

  Components: Cayenne Core Library
    Versions: 1.2
    Reporter: Andrus Adamchik
Assigned to: Andrus Adamchik
    Priority: Minor
     Fix For: 1.2

There are a bunch of issues with Hessian serialization of DataRows, making them unusable on the remote client. As of RC1, the following exception is thrown:
