Subject Re: Adding custom Tuple to a DataSet
Date Thu, 28 May 2015 08:41:13 GMT
Hi!

If you want to have type hierarchies (like base tuples and different
classes), you cannot use tuples (they are expected to be 'exact schema'),
but you can use other classes. Create your own tuple POJO with subclasses,
and it should work.
