Dynamic Tabs with dynamic content using ComponentResolver in Angular 2

Question

Inspired by Angular 2 dynamic tabs with user-click chosen components and Passing Input while creating Angular 2 Component dynamically using ComponentResolver I'm trying to go one step further and have not just the tabs get a dynamic component but also the content of be tab be comprised of dynamic components. From the original example I used components C1-C3 for the tabs and want to use C4 and C5 for sections. I'm aware there isn't any styling/functionality for actually tabbing but the structure should be enough to get me on my way. I made this.

//our root app component
import {Component, ComponentRef, Input, ViewContainerRef, ComponentResolver, ViewChild, Injectable, OnInit} from '@angular/core';

@Component({
  selector: 'dcl-wrapper',
  template: `<div #target></div>`
})
export class DclWrapper {
  @ViewChild('target', {read: ViewContainerRef}) target;
  @Input() type;
  cmpRef:ComponentRef;
  private isViewInitialized:boolean = false;

  constructor(private resolver: ComponentResolver) {}

  updateComponent() {
    if(!this.isViewInitialized) {
      return;
    }
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }
    this.resolver.resolveComponent(this.type.type).then((factory:ComponentFactory<any>) => {
      this.cmpRef = this.target.createComponent(factory);
      this.cmpRef.instance.info = this.type;
    });
  }

  ngOnChanges() {
    this.updateComponent();
  }

  ngAfterViewInit() {
    this.isViewInitialized = true;
    this.updateComponent();  
  }

  ngOnDestroy() {
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }    
  }
}

@Component({
  selector: 'child-dcl-wrapper',
  template: `<div #target></div>`
})
export class ChildDclWrapper {
  @ViewChild('target', {read: ViewContainerRef}) target;
  @Input() type;
  cmpRef:ComponentRef;
  private isViewInitialized:boolean = false;

  constructor(private resolver: ComponentResolver) {}

  updateComponent() {
    if(!this.isViewInitialized) {
      return;
    }
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }
    this.resolver.resolveComponent(this.type.type).then((factory:ComponentFactory<any>) => {
      this.cmpRef = this.target.createComponent(factory);
      this.cmpRef.instance.info = this.type;
    });
  }

  ngOnChanges() {
    this.updateComponent();
  }

  ngAfterViewInit() {
    this.isViewInitialized = true;
    this.updateComponent();  
  }

  ngOnDestroy() {
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }    
  }
}

@Component({

            <my-sections [sections]="section"></my-sections>`

@Component({

export class C2 {

@Component({

export class C4 {

})
export class C5 {

  <div *ngFor="let section of type.sections">

export class Sections {
  @Input() sections;
}

@Component({

  <div *ngFor="let tab of tabs">
    <dcl-wrapper [type]="tab"></dcl-wrapper>
  </div>
`
})
export class Tabs {
  @Input() tabs;
}

@Injectable()
export class AService {
  info = [
    {
      name: "taco",
      type: C1,
      sections: [
        {

        }
      ]
    }
  ];

  getServiceInfo() {
    console.log("Bung.");
    return this.info;
  }

@Component({

export class App extends OnInit {

  aService;

  constructor(private aService: AService) {
    this.aService = aService;
  }

  getInfo() {
    console.log("beep");
    this.types = this.aService.getServiceInfo();

  ngOnInit() {

I see several errors in your code. For example you need to use info.sections instead just section in the following code:

<my-sections [sections]="section"></my-sections>

It should be:

<my-sections [sections]="info.sections"></my-sections>

Also you forgot to add Sections directive like this:

@Component({
  selector: 'c1',
  template: `<h2>c1</h2><p>{{info.name}}</p>
            <my-sections [sections]="info.sections"></my-sections>`,
  directives: [Sections] <== add this line

})
export class C1 {}

And you can use one DclWrapper to do that.
