body: <p>I have a bizzare situation. So I have the following situation: </p>
  
  <pre><code>{% for order in aFilteredOrdersBySupplier %}
    {% set article_id = order.ref_article %}
    {{  dump(form_logistique[article_id].article_id) }}
    {{  dump(article_id) }}
    {{  dump(1903) }}

  </code></pre>
  
  <p>For this code : <code>{{  dump(article_id) }} {{  dump(1903) }}</code> I get in template : </p>
  
  <pre><code>int 1903 int 1903

  <pre><code>{{  dump(form_logistique[article_id].1903) }}
  </code></pre>
  
  <p>Work fine, but If I write : </p>
  
  <pre><code>{{  dump(form_logistique[article_id].article_id) }}

  <pre><code>array (size=2)
  1903 =&gt; 
  object(Form)[58]
    private 'a_field' =&gt; 
      array (size=2)

  object(Form)[61]
    private 'a_field' =&gt; 
      array (size=2)
        1904 =&gt; 
          object(Text)[62]
            ...
        'availability' =&gt; 
          object(Checkbox)[63]
