While get_value is actually in charge of formatting it for the widget, so if you need to change the retrieved data you just override _do_get_provider_count_and_objs and it will cascade to get_value > At the very least the comment needs to be changed.

While get_value formats the data to be displayed in a widget and performs additional conversions which are not correct for an API (like formatting dates in US format and removing any binary field and so on...) -- You received this message because you are subscribed to the Google Groups "TurboGears" group.
