Dan Haywood commented on ISIS-641:
----------------------------------
The issue isn't to do with delete, simply that Isis assumes that any returned
value of an action is either a scalar, or an object, or a java.util.List. so
we need instead to handle a return value of type java.util.Collection as well
(and convert into a java.util.List if required).
