Ich versuche, eine Komponente dynamisch von einer übergeordneten Komponente zu laden. Beim Laden der untergeordneten Komponente muss ich auch einige Eingabeparameter übergeben. In der Browserkonsole wird jedoch der folgende Fehler angezeigt.

Meine übergeordnete Komponente

import { Component, ViewChild, ViewContainerRef, ComponentResolver, Injector } from '@angular/core';
import { ExtractorDetails } from './ExtractorDetails';

declare var kendo: any;

@Component({
    selector: 'kendo-grid',
    templateUrl: './HTML/Admin/KendoGrid.html',
    providers: [Configuration, Constants ],
    directives: [Grid, ExtractorDetails]
})
export class ExtractorQueueGrid {
     @ViewChild(ExtractorDetails, { read: ViewContainerRef }) childContainer;

    options: any;
    rowObject: any;

    constructor(private configSetttings: Configuration, private constants: Constants, private _injector: Injector, private viewContainer: ViewContainerRef, private _cr: ComponentResolver) {
        this.setUpGridOptions();
    }

    onChange(event) {
        console.log("click event called");
        console.log("event " + event);
        event.preventDefault();

        this.rowObject = event.target;

        console.log("Queue ID : " + this.rowObject.parentElement.cells[0].innerText);

        this._cr.resolveComponent(ExtractorDetails).then(cmpFactory => {
                console.log("Creating component");

                this.childContainer.createComponent(cmpFactory,null, this._injector);
                let cmpRef = this.childContainer.createComponent(cmpFactory);
                cmpRef.instance.ExtractorID = this.rowObject.parentElement.cells[0].innerText; //Input paramter which need to be passed to child component 
            });
    }

}

Meine untergeordnete Komponente

import { Component, Input } from '@angular/core';

@Component({
    selector: 'extractordetails',
    templateUrl: './HTML/Admin/ExtractorDetails.html'  
})
export class ExtractorDetails {
    @Input() ExtractorID : any; 

    constructor()
    {
        console.log("ExtractorDetails component is loaded");
    }
}
