MPTtree, Hieararchical trees in a database table

Ok, I think I found the problem: the dbobj2orm() method converts only DB_result to orm objects.
So to fix that a little update to base_php5.php (or base.php) is required:

Code:

// in base_php5.php
// method dbobj2orm()

//// replace:
// fetch results
foreach($db_obj->result_array() as $row_count => $row)

//// with:
// fetch results
if( ! is_array($db_obj))
{
    $db_obj = $db_obj->result_array();
}

foreach($db_obj as $row_count => $row)
//// end replace

//// replace:
// clear db object
$db_obj->free_result();

//// with:
if(is_object($db_obj))
{
    // clear db object
    $db_obj->free_result();
}

I think that should do it.
