title: How to pass a collection/array parameters to an Action
body: <p>I am reading the documentation about the controller <a href="http://www.playframework.org/documentation/1.1/controllers" rel="nofollow">http://www.playframework.org/documentation/1.1/controllers</a> and I know how to define them on the controller side.</p>
  
  <pre><code>public static void show(Long[] id) {
      ...
  }
  or:
  
  public static void show(List&lt;Long&gt; id) {
      ...
  }
  or:
  
  public static void show(Set&lt;Long&gt; id) {
      ...
  }
  </code></pre>
  
  <p>Now, how do I call the controller and pass the array ?
  I tried </p>
  
  <pre><code>Application/show?id=1,2,3,4 
  </code></pre>
  
  <p>it doesn't work</p>
