I get this message afer it's been looping for a while:
RuntimeError: maximum recursion depth exceeded
The code producing it is a function called xmlrepr which basically takes
some basic python types and turns them into an xml document:
-- BEGIN xmlify.py --
from types import ListType, DictionaryType, InstanceType
def xmlrepr(object, name):
if type(object) =3D=3D ListType:
xml =3D "<%s>" % name
for item in object:
xml+=3D xmlrepr(item, "item")
xml =3D xml + "</%s>" % name
return xml
elif type(object) =3D=3D DictionaryType:
xml =3D "<%s>" % name
for (key, value) in object.items():
xml+=3D xmlrepr(value, key)
xml =3D xml + "</%s>" % name
return xml
else:
return "<%s>%s</%s>" % (name, object, name)
-- END xmlify.py --
The code invoking this is here:
-- BEGIN Main.py --
def list(self):
"""Lists the current entries."""
entries =3D []
for entry in Entry.select('all'):
entries.append(entry.content())
self.model =3D entries
-- END --
Where Entry is an SQLObject:
-- BEGIN entry.py --
class Entry(SQLObject):
_columns =3D [IntCol('date', default=3DNone), Col('content', =
default=3DNone),
IntCol('mood', default=3D5)]
_connection =3D SQLiteConnection('C:/Home/Projects/blog/blog.db', =
debug=3D1)
def content(self):
return {'date': self.date, 'content': self.content, 'mood': self.mood}
-- END entry.py --
Hope that helped :)

only happens to Col() or StringCol() types, IntCol() works fine.
