Gae sessions not supporting nested dictionaries.

[pradeepmantha]

Hi, I am trying to load store, nested dictionary in session in one POST handler, and retrieve it in another GET post handler. It seems somehow it is not storing nested dictionaries and it is being emptied. Below is the sample LOGS from GAE debug session.

INFO 2013-04-27 00:03:54,962 genergy.py:715] SID=1367625833_21d8679ec0f7dab4c125da6e4ea2fa3b {'after': {}, 'after_dcs': 1, 'current_dcs': 1, 'current': {1: {'dc_state': u'', 'redundancy': u'N', 'users_servers': u'option1', 'dc_type': 'Closet', 'nbr_servers': 1.0, 'nbr_users': 25.0, 'user_host': u'300', 'server_user_ratio': 1.0, 'application': 'Email', 'dc_country': u'', 'carbon': u'343'}}, 'model': 'current', 'first': True}

Could you please check , whether nested dictionary values can be stored in sessions or not.

thanks
