MappedSuperClass and inheritance problem with console generate:entities command

I have two classes.

One extends from another. I'm using the annotation @MappedSuperclass
and operates correctly, but when he did the entities generation
through the command console, doctrine adds the property and the
methods of the "father" class in the subclass.

This is a bug of the command console?

Really you should not copy them if you do not extend them. When you
run the update of the database schema, i must delete these fields and
methods added to obtain the desired result.

What happens?

Im usign Symfony 2.

Thanks!!!!

Code:

Father class:

/********************************************************************

/**

  abstract class ConfigBase
  {

/**

  *
• @param boolean $enabled
  */
  public function setEnabled($enabled) { $this->enabled = $enabled; }
  
  /**
  * Get enabled
  *
  * @return boolean
  */
  public function getEnabled()
  { return $this->enabled; }
  
  }
  
  /********************************************************************

  */
  protected $id;
  
  /**

  public function getId()
  { return $this->id; }
  
  /************************************************/
