title: Display Form Validation Error Using mkString()
body: <p>I am trying to display error messages into my view by using the in built mkString method call on my form. However the result is not as expected:</p>
  
  <p>i have:</p>
  
  <pre><code>    @productForm("name").errors().mkString(", ")
  </code></pre>
  
  <p>and the view renders the following:</p>
  
  <pre><code>    ValidationError(name,error.required,[])
  </code></pre>
  
  <p>How can i display the exact message?</p>
  
  <p>I am using play 2.1.1 (it is a java project)</p>
  
  <p>Thanks</p>
