Error in link_to in symfony admin generator

Question

I made two List actions. One actually corresponds to the default _new action and other is slightly different. So in generator.yml, I put:

  list:    
    max_per_page: 10
    title: All Posters
    display: [approved, name, user_id, _web_path, created_at]
    actions:
      upload : #this is actually equivalent to _new. 
        credentials: create_poster
        label: "Upload Poster"
        action: new
      create : 
        credentials: create_poster
        label: "Create Poster"

Now in my list view, I can see two links for these two actions but the create Link links to /poster/ListCreate/action instead of /poster/ListCreate. What can be a reason for that? I'm also pasting the _list_actions.php file in the cache.

<li class="sf_admin_action_upload">
<?php if ($sf_user->hasCredential('create_poster')): ?>
<?php echo link_to(__('Upload Poster', array(), 'messages'), 'poster/new', array()) ?>
<?php endif; ?>

</li>
<li class="sf_admin_action_create">
  <?php if ($sf_user->hasCredential('create_poster')): ?>
<?php echo link_to(__('Create Poster', array(), 'messages'), 'poster/create', array()) ?>
<?php endif; ?>

</li>
