Can't customize the HTML5 Drag and Drop Import with Metadata Form

[apx25_]

Hi,

I tried to customize the HTML5 Drag and Drop with studio, following (https://doc.nuxeo.com/display/NXDOC/How+to+Customize+the+HTML5+Drag+and+Drop+Import+with+Metadata+Form)

First problem : no effect. A 2.5 s delay is still there

Second problem : when I select "smart import with metadata" after dropping a file, I get a login screen, with "no active session" message". (!)

Here is the XML extension used, copied from https://answers.nuxeo.com/general/q/ddb9ba5def274f21b46a21f432b700d0/How-to-modify-the-form-after-a-...

(with "yourschemas" replaced by "dc" in the link element) :

<extension target="org.nuxeo.ecm.platform.actions.ActionService"
  point="actions">
 <action id="Chain.FileManager.ImportWithMetaDataInSeam"
      link="/nuxeo/dndFormCollector.faces?schema=dc&layout=dndEdit%40create@create"
      order="30" label="label.smart.import.with.md"
      help="desc.smart.import.with.md">
      <category>ContentView</category>
      <filter-id>create</filter-id>
 </action>

I also create a "Form Layout" named dndEdit, as described in documentation. (with Title, Description, and Vocabulary widgets in Creation Layout))

I can't see what is wrong and where to look for now... Thanks for help,

Patrice
