unexpected behavior modifying dict

[minskmaz]

I just picked up mongopersist again. Wondering if you could provide a sanity check for me as I’m having some trouble replicating this:

type(dm.root['stephan'].friends)
<class 'mongopersist.serialize.PersistentDict'>
dm.root['stephan'].friends[u'roger'] = Person(u'Roger')
transaction.commit()
sorted(dm.root['stephan'].friends.keys())
[u'roger', u'roy']

Please review or try the code I’ve posted here —>

ALSO! Keep in mind it has a clear_mongo() function, the call of which I’ve commented out.

Here’s the terminal output I’m getting when I run this 2x:

(gis)vagrant@jdev:/projects/gis/src/nona.gis/src/nona/gis/engine$ python mptest.py
ADDING OBJECTS
{'54794e77dc2eb91992b45502': <main.File object at 0x2ae4398>}
(gis)vagrant@jdev:/projects/gis/src/nona.gis/src/nona/gis/engine$ python mptest.py
{}

I am expecting the same output the second time (minus 'ADDING OBJECTS')
