Christophe Jelger commented on SLING-6478:
------------------------------------------
I just attached a diff to add that functionality. Note that the
{{@RequestParameter}} annotation can be used to inject {{String}}, {{Integer}},
and {{Date}} fields. The injector automatically converts integers and dates. To
inject a {{Date}}, the annotation must have the {{simpleDateFormat}} attribute
which defines the conversion format. I added these basic converters to be able
to define a Sling model that can represent a basic HTML form with text,
integer, and date input fields.
Following the discussion thread
http://apache-sling.73963.n3.nabble.com/Sling-Model-and-Request-Parameters-tt4065648.html#a4065663,
the injector ensures that a request parameter is only injected if and only if
the {{@RequestParameter}} was used. That is, the injector returns null if
{{@Inject}} was used.
