How to name a template file for the following theme hook suggestions? I hardly managed it to create theme hook suggestions to work with different bean blocks, so I can use custom .tpl files like:

bean--{bundle_name}.tpl.php // currently only bunde is 'zielgruppe'


Here is the code so far:

/**
 * Override or insert variables into the block templates.
 */
function mymodule_preprocess_block(&amp;$variables) {
  // For bean blocks.
  if ($variables['block']-&gt;module == 'bean') {
    // Get the bean elements.
    $beans = $variables['elements']['bean'];
    // There is only 1 bean per block.
    $bean = $beans[reset(element_children($beans))];
    // Add bean type classes to the parent block.
    $variables['classes_array'][] = drupal_html_class('bean-' . $bean['#bundle']);
    // Add template suggestions for bean types.
    $variables['theme_hook_suggestions'][] = 'bean__' . $bean['#bundle'] . '_tile';
    $variables['theme_hook_suggestions'][] = 'bean__' . $bean['#bundle'] . '_' . $bean['#entity']-&gt;delta;
  }
}


But for the last suggestion I just cant figure how to freakin name the file. delta prints "für-angehende-lehrkräfte". I've tried to following file names which dont get noticed:

bean--zielgruppe-für_angehende_lehrkräfte.tpl.php
bean--zielgruppe-für-angehende-lehrkräfte.tpl.php


(appearently stack messes up ü characters in code areas)

For instance, bean--zielgruppe-tile.tpl.php works.
You can also output the theme_hook_suggestion with DSM. You'll see all the suggestions and template candidates for your content. (https://drupal.org/project/devel_themer could help you too)
