--------------------------------------
Hi [~joerghoh], just curious how would you go about defining optional as
default injection strategy?
E.g.
{code:java}
@Model(adaptables = Resource.class, defaultInjectionStrategy =
DefaultInjectionStrategy.OPTIONAL)
public class SomeModel {
{code}
Would this require to implement all class attributes as optional? And if not
compilation error?
> Injections for java.util.Optional<> should be automatic optional

> The current approach to support optional injections requires to annotate the
> field with {{@Optional}} plus proper handling within the javacode (null
> checks etc), which can be forgotten.
> So instead of
> {code}
> @Inject @Optional
> String fieldname;
> {code}
> it should also be possible to use this
> {code}
> @Inject
> Optional<String> fieldname;
> {code}
> with the very same semantic. But the developer is forced to deal with the
> case that the value is not present.
