Access token does not extend to View/Edit tabs (Anonymous users)

I think you can accomplish this using something like the solution proposed in #1344902: Provide an optional destination parameter for local actions. I don't see webform customizing its menu tabs for this, but I'm happy to listening to additional discussion from others about the technical merits. If so, please re-open with discussion.

I've tesame issue here.
My setup :
- Drupal 7
- In the webform permissions, anonymous users can edit/delete there own submissions.
- In the confirmation page (and mail) i use the access token : <p>Go to your submission: <a href="/node/[node:nid]/submission/[submission:sid]?token=[submission:access-token]">Submission [submission:serial]</a></p>
This produce me a link to 'http://my.wwwdev.be/node/5354/submission/17262?token=af6fa8343c4e09e40ed...'
When the anonymous user use on this link, he can see his submission and in the admin-tabs there are three links.
'View' -> 'http://my.wwwdev.be/node/5354/submission/17262'
'edit' -> 'http://my.wwwdev.be/node/5354/submission/17262/edit'
'delete' -> 'http://my.wwwdev.be/node/5354/submission/17262/delete'
All three without the token. So when the anonymous users klicks on these link, he gets een 'access denied'.
If these links where appended with the token, the links will work for the anonymous users.

I can't get the provided solution (https://www.drupal.org/node/1344902) to work in drupal 7

Sorry to re-activate this issue.
I will close it again because i solved it in Drupal 7 with hook_menu_local_tasks_alter :

function yourmodule_menu_local_tasks_alter(&$data, $router_item, $root_path) {
  if (user_is_anonymous() && !strcmp($root_path,'node/%/submission/%') && isset($_GET['token'])) {
    $mytoken = $_GET['token'];
    foreach ($data['tabs'][0]['output'] as &$link) {
      $link['#link']['localized_options'] = array('query' => array('token' => $mytoken));
    }    
  }
}

Thanks @pbosmans,

I think your solution of using hook_menu_local_tasks_alter is the best.

Code in #5 works.
Bur when you edit the submission by clicking the button "save". You get the message "Acces denied" because the save button does nog know the access token.. How can you solve this?

* EDIT *
By using the acces token in the destination, this is solved
