are you using objectstore.clear() anywhere ? if so, all objects that
have been loaded or saved with the mapper must be discarded (or
imported) before continuing.

Hello first sorry for my poor English,
i'm creating a GUI application using PyGTK, and i chose to use
SQLAlchemy mapping. I get this error, without starting any thread and
everything seems to be linear:

the current thread's Identity Map: '%s'. Use
objectstore.import_instance() to place deserialized instances or
instances from other threads" % repr(obj._instance_key))
NameError: global name 'InvalidRequestError' is not defined
Sometimes i solved this error by doing an import_instance or fixing
problems after clearing the objectstore, but now i'm getting really
bored of that... tell me if you need more informations.
