Edit, download, delete operations not working with latest media.

Yes. THIS is SOOOO frustrating

Same issue here.

I debugged this a bit. I asume you are on the latest dev of media. The reason why this is not working anymore is that the bulk functionality has been moved into a submodule here: #2143469: Spin-off bulk file upload support in dedicated module / project

Commit:
http://drupalcode.org/project/media.git/commit/81640ea480a4d19433523c525...

So the hook_menu() implemetations are not correct any more.

e.g.:

  // Expose further "Mutliple" actions.
  if (module_exists('multiform')) {
    // Following approach comes from the media module.
    // @todo Investigate passing file IDs in query string rather than a menu
    // argument and then deprecate media_multi_load().
    $items['admin/content/file/delete-multiple/%media_multi'] = array(
      'title' => 'Delete multiple files',
      'page callback' => 'drupal_get_form',
      'page arguments' => array('file_entity_multiple_delete_confirm', 4),
      'access callback' => TRUE,
      'access arguments' => array('delete', 4),
      'file' => 'file_entity.admin.inc',
      'file path' => drupal_get_path('module', 'file_entity'),
    );
  }

Needs now to be:

  // Expose further "Mutliple" actions.
  if (module_exists('multiform')) {
    // Following approach comes from the media module.
    // @todo Investigate passing file IDs in query string rather than a menu
    // argument and then deprecate media_multi_load().
    $items['admin/content/file/delete-multiple/%media_bulk_upload_multi'] = array(  // PATH HAS CHANGED HERE
      'title' => 'Delete multiple files',
      'page callback' => 'drupal_get_form',
      'page arguments' => array('file_entity_multiple_delete_confirm', 4),
      'access callback' => TRUE,
      'access arguments' => array('delete', 4),
      'file' => 'file_entity.admin.inc',
      'file path' => drupal_get_path('module', 'file_entity'),
    );
  }

This needs to be changed on several places. I will fix this today on my current project and send a patch later.

Patch attached. There was already a fix for download and edit in the latest dev. I copied this over to the part responsible for deleting.

Attention:
You need to activate the "media_bulk_upload" module which is a submodule from media to make this work. This should normally happen in an hook_update() the code is there but for some reason it was still disabled on my side.

Updating title, it is more likely that people search for delete if deleting stuff is not working than for operations. So let's make it a bit clearer what this is about.

Thanks :)
