[FLOW3-general] No class schema found for "Doctrine\Common\Collections\Collection"

[Daniel Siepmann]

Hi,

I've got the same problem.
I created the models but there is something special to my models.
There is one Model "Person" (which is an abstract class) and the two 
models "Student" and "Teacher".
They extend "Person". I created a repository for "Person" only yet. I 
don't know, is this the right way?

Here is the exception from cli:
================
Uncaught Exception
  No class schema found for "Doctrine\Common\Collections\Collection". The
  class should probably marked as entity or value object!

More Information
  Exception code      #1295973082
  File

line 80

And here is my package as zip-file for download:
