[SQLObject] _SO_createValues should be emptied uppon expire()?

[Andres F. <an...@an...>]

Hi,

im not sure if it really is a problem, but after looking quite some 
time at sqlobject im still not sure if my Problem is really one, so 
here is the idea of it.

>>> person.sqlmeta.lazyUpdate = True
>>> person.username = "somename"
>>> print person.username
"myname"
>>> person.username = "yourname"
>>> person.expire()
>>> person.sync()

The last thing would, if I'm correct, send "yourname" to the database. 
Perhaps I have overlooked something, but to me it seems to me, that a 
line alike
_SO_createValue = {}
should be put into expire().

Greetings,
