You cannot store your own classes in the session. This is because the
session is retrieved automatically for you before your controller is
called and outside the scope where the function is defined.
This is a general problem with Python.
Try this:
import picke
class A: pass
pickle.dump(A(),open('afile.pickle','w'))
Then from a DIFFERENT program
import pickle
print pickle.load(open('afile.pickle','r))
the load will fail because class A is not define there.
