How to make sfPropelCustomJoinHelper work with propel1.3?

sfPropelCustomJoinHelper is one of my favorite classes.. It’s saved me from writing headache propel joins. But it was designed to work only with propel 1.2.
So, how to make it work with propel 1.3?. Yes, you are right, extends it and override some functions.

Update:
There is no way to override hydrate function of sfPropelCustomJoinObjectProxy, because rs parameter is restricted to Resultset type.

<?php
class mysfPropelCustomJoinObjectProxy extends sfPropelCustomJoinObjectProxy
{
  public function myHydrate($rs, $startcol = 0)
  {
     $startcol = $this->obj->hydrate($rs, $startcol);
     return $startcol;
  }
}

class mysfPropelCustomJoinHelper extends sfPropelCustomJoinHelper
{
  public function __construct($mainClassName)
  {
    parent::__construct($mainClassName);
  }

  public function doSelect($c, $con=null)
  {
    $rs = $this->doSelectRS($c, $con=null);
    $a = array();
    while ($row = $rs->fetch(PDO::FETCH_NUM)) {
	$a[] = $this->hydrate($row, 0);
    }
    return $a;
  }

  public function doSelectRS($criteria, $con=null)
  {
    $c = clone $criteria;
    $c->clearSelectColumns();
    call_user_func(array($this->mainClassName.'Peer', 'addSelectColumns'), $c);
    foreach ($this->selectClasses as $className) {
      call_user_func(array($className.'Peer', 'addSelectColumns'), $c);
    }
    $rs = call_user_func_array(array($this->mainClassName.'Peer', 'doSelectStmt'), array($c, $con));
    return $rs;
  }

  public function hydrate($rs, $startCol=1)
  {
    $obj = new mysfPropelCustomJoinObjectProxy($this, $this->mainClassName);
    $startCol = $obj->myHydrate($rs, $startCol);
    $childObjs = array();
    foreach ($this->selectClasses as $className)
    {
      $childObj = new mysfPropelCustomJoinObjectProxy($this, $className);
      $startCol = $childObj->myHydrate($rs, $startCol);
      if ($childObj->isAllPrimaryKeyNull())
        $childObjs[$className] = null;
      else
        $childObjs[$className] = $childObj;
    }
    foreach ($childObjs as $childClassName => $childObj)
    {
      $obj->addExternalObject($childObj, $childClassName); //main class object always holds all child objects.
      if (isset($this->classOwnership[$childClassName]))
        foreach ($this->classOwnership[$childClassName] as $tmp)
          if (array_key_exists($tmp[0], $childObjs))
            $childObj->addExternalObject($childObjs[$tmp[0]], $tmp[1]);
    }
    return $obj;
  }
}

Sorry for my bad english :D..
I hope it help.
