[SQLObject] value cache and validators

[alexander s. <al...@an...>]

hello!

i think there is a bug in SQLObject attribute value cache: when 
'_cacheValues' is set, an attribute getter is replaced by value written 
to data base.  if attribute is converted by Validator (fromPython), 
later access will return DB value for the attribute, and not it's 
"pythonic" representation.

merry Christmas!
