#1551: Subclass of column aggregation inheritance returns parent class instead
of
subclass

-----------------------------------+----------------------------------------
I'm using a type column to define subclasses of a base type. One of the
subclasses has an additional subclass not determined by the type column.
When I use that subclass table object to fetch objects, they are returned
as the parent class instead of the subclass.
For example:
Base class: Object
Column type subclasses: Page, File, Stylesheet (using the "type" column in
the "object" table)
Additional subclass: Template extends Page
When I do a:
$coll = Doctrine::getTable('Template')->createQuery()...
->execute();
I get back "Page" objects instead of "Template" objects.
This is a patch that fixes this problem:
