OneToMany/ManyToOne SchemaException
I try to build a manyToOne relation for my Symfony2 application with Doctrine2. I get this error and I don't know why:

app/console doctrine:schema:create
PHP Deprecated:  Comments starting with '#' are deprecated in /etc/php5/cli/conf.d/mcrypt.ini on line 1 in Unknown on line 0
ATTENTION: This operation should not be executed in an production enviroment.

                                                                     
  [Doctrine\DBAL\Schema\SchemaException]
  There is no column with name 'activityGroup' on table 'activity'.  


Those are the two classes: http://pastebin.com/Ev7Rwgxr

I think there actually IS activityGroup on the Activity class... so what does that error try to say?

Thanks!
