title: Angular2 Iterating ngFor JSON-File
body: <p>I´m fairly new to Angular2, and i want to read out a json file. It´s working, that I get the file from a REST-Client, i can save the file in a local variable in a component. Now I´m trying to read properties (Array) with ngFor, but this isn´t working. 
  Here´s the html:</p>
  
  <pre><code>&lt;div *ngFor="let categories of tasks.tasks"&gt;
      {{categories}} --&gt; Display name of categorie (epg, recs)
      &lt;p *ngFor="let task of categories"&gt;{{task.text}}&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And the JSON-File:</p>
  
  <pre><code>{
      "tasks": {
          "epg": [{
              "text": "\\\\...\\Daten\\Videos\\Aufnahmen"
          }, {
              "text": "C:\\Users\\...\\Desktop"
          }],
          "recs": [{
              "text": "\\\\...\\Daten\\Videos\\Aufnahmen"
          }, {
              "text": "C:\\...\\Junias\\Desktop"
          }]
      }
  }
  </code></pre>
  
  <p>Hope someone can help me ;)</p>
