[Mailman-Developers] GSOC:Populating two default styles

[Harshit Bansal]

Hi,
I was trying to populate the two default styles in the database. For
this purpose, I was trying to use ConfigurationUpdatedEvent as used in
the earlier style manager but I am recieving following error:

Traceback (most recent call last):
  File "/home/harshit/Drive1/dev/Mailman/mailman/src/mailman/testing/layers.py",
line 87, in setUp
    initialize.initialize_1(INHIBIT_CONFIG_FILE)

line 513, in __getattr__
    raise AttributeError("No section or category named %s." % name)
AttributeError: No section or category named db.

It seems that the database layer hasn't got initialized by the time
this event was fired. Is there any way of fixing this or any other way
using which I can populate the database when mailman starts?

Thanks,
