Symfony 1.3: different form filters generated

Question

Hi,

i have this class in rs1/lib/filter/doctrine/FelizFormFilter.class.php

<?php

/**
  * Feliz filter form.
  *
  * @package    rs
  * @subpackage filter
  * @author     Your name here
  * @version    SVN: $Id: sfDoctrineFormFilterTemplate.php 23810
2009-11-12 11:07:44Z Kris.Wallsmith $
  */
class FelizFormFilter extends BaseFelizFormFilter
{
   public function configure()
   {
   }

}

and this in rs2/lib/filter/doctrine/FelizFormFilter.class.php

<?php

/**
  * Feliz filter form.
  *
  * @package    filters
  * @subpackage Feliz *
  * @version    SVN: $Id: sfDoctrineFormFilterTemplate.php 11675

  */
class FelizFormFilter extends BaseFelizFormFilter
{
   public function configure()
   {
   }

}

Both were generated using "php symfony doctrine:build --all --and-load" and the version of symfony is 1.3.4 in both.

This is the schema of both cases:

Feliz:
   columns:
     name: string(20)

Could you tell me why are different?

One more thing in Eclipse: when i go with the mouse pointer to the word "BaseFelizFormFilter", in the second case (rs2) the yellow window with the information about the class is showed, but in the first case that yellow popup is not showed. Why?
