[Flask] Issues with Flash_session - Cannot add dict item ..

[Ben Duncan]

Thanks for all the help ...

Here is the code

session = Session()
print "Session type is --------", type(session)
session.init_app(app)
print "Session init type is --------", type(session)
print "Dir of session is:", dir(session)

session = {'modified': False }

As noted, from my earlier post, it looks like a dictionary needs to be
initialized with a dictionary.
Once I did this, all is well in never-never land

Local IT even fixed my borken desktop ...
