> Project: Isis
> Issue Type: Improvement
> Components: Core
> Affects Versions: core-1.3.0
> Reporter: Oscar Bou
> Assignee: Dan Haywood
> Attachments: patch.diff
>
>
> Current implementation only allows to return a List with the choices for a
> given property, action or action parameter.
> It should be improved to allow to return any descendant of
> java.util.Collection.
> All these cases should be valid:
> class Customer {
> @SuppressWarnings("unused")
> public void someAction(final int x, final long y, final long z) {
> }
>
> @SuppressWarnings("unused")
> public Collection<Integer> choices0SomeAction() {
> return Collections.emptyList();
> }
>
> @SuppressWarnings("unused")
> public List<Long> choices1SomeAction() {
> return Collections.emptyList();
> }
> @SuppressWarnings("unused")
> public Set<Long> choices2SomeAction() {
> return Collections.emptySet();
> }
> }
