Bug with Criteria::fromInput and Model::columnMap?

Hi everyone,

I think I might have hit a bug in Phalcon with Criteria::fromInput and Model::columnMap.

I have a database table called "localized_languages" with fields "id", "language_id", "localized_language_id" and "name". In my controller I have the following code to search for localized languages:

    $this->view->pick("localized-languages/search");
         $numberPage = 1;
         if ($this->request->isPost()) {
             $query = Criteria::fromInput($this->di, 'My\Models\LocalizedLanguages', $this->request->getPost());
             echo var_dump($query);
             $this->persistent->searchParams = $query->getParams();
         } else {
             $numberPage = $this->request->getQuery("page", "int");
         }

         $parameters = array();
         if ($this->persistent->searchParams) {
             $parameters = $this->persistent->searchParams;
         }

         $localizedLanguages = LocalizedLanguages::find($parameters);
        (...)

Now in my model I have the following column mappings:

      public function columnMap()
      {
          return array(
              'id' => 'id',
              'language_id' => 'languageId',
              'localization_language_id' => 'localizationLanguageId',
              'name' => 'name'
          );
      }

If I execute this code, a var_dump of the $query object gives me the following:

object(Phalcon\Mvc\Model\Criteria)#138 (3) { ["_model":protected]=> string(34) "My\Models\LocalizedLanguages" ["_params":protected]=> NULL ["_hiddenParamNumber":protected]=> int(0) } 

As a result, $parameters remains an empty array and I get back the complete list of "Localized Languages" instead of a list filtered by localizationLanguageId.

The following query is generated:

[Fri, 10 Oct 14 14:56:05 +0200][INFO] SELECT `localized_languages`.`id`, `localized_languages`.`language_id`, `localized_languages`.`localization_language_id`, `localized_languages`.`name` FROM `localized_languages`

BUT: if I comment the columnMap function and delete the metadata, then var_dump($query) gives me the following:

object(Phalcon\Mvc\Model\Criteria)#138 (3) { ["_model":protected]=> string(34) "My\Models\LocalizedLanguages" ["_params":protected]=> array(2) { ["conditions"]=> string(51) "localization_language_id=:localization_language_id:" ["bind"]=> array(1) { ["localization_language_id"]=> string(2) "39" } } ["_hiddenParamNumber":protected]=> int(0) } 

Criteria now has parameters, so I get back the correct list. The following query is generated:

[Fri, 10 Oct 14 14:51:37 +0200][INFO] SELECT `localized_languages`.`id`, `localized_languages`.`language_id`, `localized_languages`.`localization_language_id`, `localized_languages`.`name` FROM `localized_languages` WHERE `localized_languages`.`localization_language_id` = :localization_language_id

Am I missing something very obvious here, or is this indeed a bug?
