Justin Edelson commented on SLING-7187:
---------------------------------------
bq. 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.
Yes, that's the whole point :) since the optional attribute is set to false by
default.
bq. I would just like to highlight that the optional attribute is anyhow
deprecated since SLING-4155 and instead the injectionStrategy attribute should
be used.
The problem is that even if someone doesn't use it, it is still set. I guess
the other alternative to this would be to remove support for the optional
attribute entirely (i.e. just ignore it if set). I don't think we need to do
that.

> Issue Type: Bug

> 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.
