title: Play - Scala Template, access list element
body: <p>I have two arraylists, <code>Tweets: ArrayList[TweetObject]</code> and </p>
  
  <pre><code>cluster_sizes: ArrayList[Integer]
  </code></pre>
  
  <p>What i want to do is this but i couldn't find a way to do it, I don't want to mess with the TweetObject class to add what is in the cluster_sizes array.</p>
  
  <pre><code>@for((tweet,index) &lt;- Tweets.zipWithIndex){
      @form(action = routes.Application.clean_and_move_on()){
          &lt;td&gt;@index&lt;/td&gt;
          &lt;td&gt;@cluster_sizes[@index]&lt;/td&gt;
          &lt;td&gt;@tweet.owner&lt;/td&gt;
  </code></pre>
  
  <p>Is there any way to access this list like <code>@cluster_sizes[@index]</code> ?</p>
