Missing forwardRef in ViewChild/ViewChildren should throw #4489
Description
Follow up of #4174
I'm updating this issue to a38, still reproducible. I added an issue with @ViewChild that returns null instead when there's no forwardRef.
@View({
template : `
<child></child>
<child></child>
`,
directives: [forwardRef(() => Child)]
})
class Parent implements AfterViewInit {
// Length : 2
//@ViewChildren(forwardRef(() => Child)) children: QueryList<Child>;
// Length : 0
@ViewChildren(Child) children: QueryList<Child>;
// Returns the child
//@ViewChild(forwardRef(() => Child)) child : Child;
// Returns null
@ViewChild(Child) child : Child;
afterViewInit() {
console.log(this.child);
console.log(this.children);
}
}
@Component({selector : 'child'})
@View({template : 'I\'m a child!'})
class Child {}Again, I assume that ContentChild/ContentChildren works the same way that ViewChild/ViewChildren so I didn't test the issue against both of them.

Same issue is valid for
ContentChildrenandContentChildas well. I'm working on this issue.ericmartinezr commentedon Apr 27, 2016
