hi

just upgraded from 0.5.2 to the svn version.

code like this:

	class Sub(SQLObject):
		...

	class Person(Sub):
		_fromDatabase = True

which used to work in 0.5.2, now produces:

Traceback (most recent call last):
  File "test.py", line 31, in ?
    class Person(Sub):
  File "/usr/lib/python2.3/site-packages/sqlobject/main.py", line 159, in 
__new__
    newClass.addColumnsFromDatabase()
  File "/usr/lib/python2.3/site-packages/sqlobject/main.py", line 460, in 
addColumnsFromDatabase
    for columnDef in cls._connection.columnsFromSchema(cls._table, cls):
AttributeError: 'NoneType' object has no attribute 'columnsFromSchema'


incidently, i found out that the following does work, though:

	class Sub(SQLObject):
		...
	class SubSub(Sub):pass

	class Person(SubSub):
		_fromDatabase = True


and actually, my current setup now requires a SubSubSub class...
am i missing something?

lg
