Hi Thomas, The reason I want to be able to rollback (but still commit by log entries) is because it is sometimes valid for this particular view to throw an exception and fail. If this happens, I need to rollback any model objects that have been created and saved up to the point at which the view fails (again, except for any logging that has been done). The view contains a big try/except statement and the rollback is in the "except" part.
I may have to approach this a different way, because it doesn't look like I can easily do a fine-grained commit.
