Konrad Windszus commented on SLING-7187:
----------------------------------------
The patch in general looks fine but it would modify the behavior in case both
the optional attribute is set to {{false}} as well as the @Optional annotation
is set, as with your patch the @Optional would take precedence. But since this
would be rather unexpected I don't think this is a problem.
I would just like to highlight that the optional attribute is anyhow deprecated
since SLING-4155 and instead the injectionStrategy attribute should be used.
> Use of Injector-specific annotation and @Optional results in required-value

> If there is a model class like
> {code}
> @Model(adaptables = Resource.class)
> public class ModelClass {
> @ValueMapValue
> private String otherText;
> @Override
> public String getOtherText() {
> return otherText;
> }
> @ValueMapValue
> @Optional
> private String emptyText;
> @Override
> public String getEmptyText() {
> return emptyText;
> }
> }
> {code}
> It would be a reasonable expectation that the {{emptyText}} field will be
> optional. But that is not actually the case since the {{@ValueMapValue}} has
> a default {{optional}} attribute of {{false}}.
> Can be worked around by using {{@ValueMapValue(optional = true)}} instead of
> having the separate {{@Optional}} annotation.
