The problem resided in Item_window_func implementation, and it was revealed by bb-10.2-ext specific changes: Item_window_func::save_in_field() works differently in bb-10.2-ext vs 10.2: - 10.2 goes through val_str() - bb-10.2-ext goes through get_date(), due to Type_handler related changes. get_date() tries to convert empty string to DATETIME, hence the warning. During a discussion with Vicentiu, it was decided to fix Item_window_func::val_xxx() to return NULL (instead of an "empty" value, such as 0 for numbers and '' for strings) when force_return_blank is set.
