title: @FormParam only receives empty list/array (Apache Wink)
body: <p>I'm using Apache Wink for implementing REST Services and I can't seem to receive parameters of type array or List. The call is being made from ajax $.post: </p>
  
  <pre><code>$.post(url,
      {   param: ['string1', 'param2', 'x', 'etc...etc....etc'], 
          str2: "str2"},
      function(data) {// do something     
  }); 
  </code></pre>
  
  <p>On the server side, Strings and ints are correctly received, but the 'param' parameter is always received empty (not null, but with zero elements), whether the variable is defined as String[], List, Set, ... . The receiving function is defined as: </p>
  
  <pre><code>@POST @Produces("application/json") @Path("eee") 
  public Response eee(@FormParam("str1") String str1, @FormParam("param") String[] param, @FormParam("str2") String str2)
  </code></pre>
  
  <p>While debugging, I can see a context variable with a table entry like:</p>
  
  <pre><code>wink.formParameters=[param%5B%5D=string1,param%5B%5D=param2,param%5B%5D=x,param%5B%5D=etc...etc....etc,str2=str2]
  </code></pre>
  
  <p>That translates to 'param[]=string1, param[]=param2, ..', no indexation. Don't know if that's correct. </p>
  
  <p>Any ideas ? </p>
