title: changing form action with play 2.0
body: <p>I'm trying to render a form with action POST using play 2.10</p>
  
  <pre><code>@form(action = routes.Application.sentiment, args = 'id -&gt; "helloform", 'method -&gt; "POST")
  </code></pre>
  
  <p>The output for this is (I verified this in play console)</p>
  
  <pre><code>&lt;form action="/sentiment" method="GET" id="helloform" method="POST"&gt;
  </code></pre>
  
  <p>The net effect of this in a browser is it ends up ignoring the second method attribute. What am I doing wrong? How do I override the default form method?</p>
