Support for group conversion
While cascading a data validation, it may happen that the data to validate belongs to
groups that are different from the requested group. For a concrete example, consider
the following two classes
Student
and
Address
:
public class Student {
@NotNull
@Size(min = 1, max = 15)
private String id;
