4.0.0-rc.6 regression: using @Input() @ContentChild() on the same property breaks input

I'm submitting a ... (check one with "x")

[ x] bug report => search github for a similar issue or PR before submitting

Current behavior

Given the property that has both @input() and @ContentChild() annotations breaks the @input(). Ex.: @Input() @ContentChild(TemplateRef) tpl: TemplateRef<any>;

Expected behavior

Using @Input() and @ContentChild() on the same element should be supported as it used to be in 2.x or clearly documented as not supported.

Minimal reproduction of the problem with instructions

Observed behaviour: prints: "default, Custom as a child, default"

Expected behaviour: prints: "default, Custom as a child, Custom as a binding"

What is the motivation / use case for changing the behavior?

In ng-bootstrap we've got the API that let's users provide a custom rating template either as a binding or as a child template: https://github.com/ng-bootstrap/ng-bootstrap/blob/5856a75ace90c7323d073f1a9838560016bbb5d4/src/rating/rating.ts#L96

Besides it is a regression, you can confirm that it used to work by changing ANgular version in the config.js file in the linked plunker.

• Angular version: 4.0.0-rc.6, used to work in 2.4.10
