I am trying to implement a @Strategy using the FieldStrategy interface. The
problem I am having is that when I go to persist my object it is always
going with the default handlers. I am not receiving any exceptions until it
goes to do the insert. I am wondering if I have done this correctly or not
so any feedback is appreciated.
