currently having an object in my temporary data context with

not normal, is it?  This particular problem might be caused by how I
was doing my serialization of DataObjects in the session-scoped data
context (that context is not serialized, only the objects are).

Yeah, it's looking like this one was a self-inflicted problem.

I threw in some extra code in my base DataObject:

   private void writeObject(java.io.ObjectOutputStream out)
   throws IOException
   {
       out.writeBoolean(Boolean.TRUE ==
this.getDataContext().getUserProperty("temporary"));
       out.defaultWriteObject();
   }
   private void readObject(java.io.ObjectInputStream in)
   throws IOException, ClassNotFoundException
   {
       boolean isInTemporaryDataContext = in.readBoolean();
       in.defaultReadObject();
       this.isInTemporaryDataContext = isInTemporaryDataContext;
   }


and then conditionally attach to the thread-bound datacontext only if
isInTemporaryDataContext is false, and that appears to have solved
this problem.
