Subject Re: Enhancement skipping field
Date Tue, 12 Jul 2011 20:58:21 GMT
Hey Rick,
  Adding the handler makes the field appear in the field list for my
plugin.  However my plugin currently doesn't support value handlers.  I
need to add this functionality, what is the best class to use as an
example for reading this meta data and invoking it at runtime?

Thanks,
Todd
