[FLOW3-general] Flow3 Party package

[indira]

Hi everyone,
I have been trying to get the authentication process working using the 
Party package, but I am new to Flow3 and Doctrine and I still can't get it 
to work.

I have a Trainee and Trainer model and they are inheriting the Person 
model. However, I believe I need to add some annotations to Person 
(InheritanceType and/or DiscriminatorColumn) ?
In addition, I have a OneToMany relation between Trainer and Trainee. 

When trying to add a trainee with the name 'Trainee One' I get this error:

#1297759968: Exception while property mapping for target type 
"STW\FITNESSONE\Domain\Model\Trainee", at property path "name": Object with 
identity "Trainee One" not found.


Thanks in advance,
Indira.
