------------------------------------------

> Mixin property annotated using @Property(projecting=...) not picked up in the
> MM.
> ---------------------------------------------------------------------------------
>
> Key: CAUSEWAY-3540
> URL: https://issues.apache.org/jira/browse/CAUSEWAY-3540
> Project: Causeway
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0-RC2
> Reporter: Daniel Keir Haywood
> Priority: Minor
>
> The use case is that I had an entity (OutgoingInvoice) and also a view model
> (OutgoingInvoiceView), with the view model being based on the entity but
> having more information.
> What I wanted to do was have a query return a list of entities (because that
> is very fast, avoids the n+1 orm problem), but then when the user clicks on
> an entity icon from the list, then to open up the view instead.
> This works fine if I declare the "projecting" property as a regular property
> on the entity:
> {code:java}
> @Property(projecting = Projecting.PROJECTED)
> @PropertyLayout(hidden = Where.EVERYWHERE)
> public OutgoingInvoiceView getView() {
> return new OutgoingInvoiceView(this);
> }{code}
> However, this makes the entity (dom layer) aware of the view (app layer),
> which I didn't much like. So I wanted instead to have a mixin in the app
> layer contribute to the entity ... but it doesn't get picked up:
> {code:java}
> @Property(projecting = Projecting.PROJECTED)
> @PropertyLayout(hidden = Where.EVERYWHERE)
> @RequiredArgsConstructor
> public static class view() {
> private final OutgoingInvoice entity;
> @MemberSupport public OutgoingInvoiceView prop() {
> return new OutgoingInvoiceView(entity);
> }
> }{code}
>
