body: <p><strong>How to hide save button on popup form?*</strong></p>
  
  <p>The form view opened by action in python code.
  I already tried some recommended solution, but their doesn't work.</p>
  
  <p>Some portal/forum said this flags will be solve it. But it don't, what even more, it has not any effect to behavior. (anyway, where can I read from flags? I can't find any useful description about it.)
  </p>
  
  <pre><code>@api.multi
  def button(self):
      viewId = self.env.ref('Model.model').id
      return {
          'name': _('Button action'),
          'view_type': 'form',
          'view_mode': 'form',
          'view_id': viewId,
          'res_model': 'model',
          'type': 'ir.actions.act_window',
          'res_id': self.id,
          'target': 'new',
          'flags': {'form': {'action_buttons': False}}
      }
  </code></pre>
  
  <p>The most place said this is the right way, but it does not work...
  </p>
  
  <pre><code>&lt;record id="model" model="ir.ui.view"&gt;
          &lt;field name="name"&gt;model&lt;/field&gt;
          &lt;field name="model"&gt;model&lt;/field&gt;
          &lt;field name="arch" type="xml"&gt;
              &lt;form string="Button form" edit="false" create="false" delete="false"&gt;
                  &lt;group&gt;
                      &lt;field name="test" /&gt;
                      &lt;button name="myButtonFunc" string="Demo button" icon="fa-plus" type="object"/&gt;
                  &lt;/group&gt;
              &lt;/form&gt;
          &lt;/field&gt;
      &lt;/record&gt;
  </code></pre>
  
  <p>Any idea? Or experience with it?</p>
