I define a new Document Type “montype” with a new icon like this :

  <type id="montype">
      <label>Mon Nouveau Type</label>
      <icon>/icons/montype-16.png</icon>
      <bigIcon>/icons/montype-100.png</bigIcon>
      <category>SimpleDocument</category>
      <description>montype.description</description>
      <default-view>view_documents</default-view>
      <layouts mode="any">
         <layout>montype</layout>
         <layout>file</layout>
      </layouts>
    </type>

NuxeoDM show the new icon “montype.png” when i create an instance without a file joined but when i join a file (like an image or an excel file for instance), nuxeoDM show the image's icon or excel's icon instead of my montype-16.png. It is a bug or is there a way to keep my new Document Type's icon ?

Thanks !
