Query annotation doesn't work with typescript and alpha 28 #2916
Description
... or I'm doing something terribly wrong of course. I have this basic example:
/// <reference path="typings/angular2/angular2.d.ts" />
import {Query, QueryList, Component, View, bootstrap} from "angular2/angular2";
@Component({
selector: 'd'
})
@View({
template: ``
})
class D {
}
@Component({
selector: 'c'
})
@View({
template: ``,
directives: [
D
]
})
class C {
constructor( @Query(D) ds: QueryList<D>) {
console.log(ds);
}
}
@Component({
selector: 'app'
})
@View({
template: `
<c>
<d></d>
<d></d>
<d></d>
</c>
`,
directives: [
C,
D
]
})
class App {
}
bootstrap(App);When I run this code the logging in the console is this:
QueryList {_results: Array[0], _callbacks: Array[0], _dirty: false}
Why are there no results? Also adding {'descendants': true} has no effect...

QueryList is a live list that is updated by change detection. As such construction time is too early to see the D directives.
To be notified of changes you can attach a callback using
