Hello,

I have a single table inheritance setup with an abstract base class and 2 concrete classes, like:
/****

@Entity
@Table(name="entry")
@InheritanceType("SINGLE_TABLE")
@DiscriminatorColumn(name="is_news", type="integer")
@DiscriminatorMap({"1" = "Popshouse\SiteBundle\Entity\News", "0" = "Popshouse\SiteBundle\Entity\Promotion"})
@HasLifecycleCallbacks
_/
abstract class Entry
/_***
- @Entity
  _/
  class News extends Entry{
  public function *_construct(){
  //do stuff
  }
  ...
  }

When I do $em->find('News',$id);
It creates the correct News object, but it hasn't called the constructor (so stuff "//do stuff" hasn't been executed). No problem when manually creating new News() object.

Comment created by @beberlei:

Not calling the constructor is done by design, not a bug:

http://www.doctrine-project.org/docs/orm/2.0/en/reference/architecture.html#entities

Use @postLoad to perform operations for entities when they are reconstructed from the database.
