SQL & PL/SQL :: Bulk Collections And Current OF

I have a driver table from which I need to update another table while, at the same time, record the fact that I have processed each record on the driver table.

The driver table will contain around 3.5 million records, therefore I intended to handle this using some bulk collections, with a LIMIT option so that I don't hit any memory problems.

I would also prefer to commit in batches, or at least handle exceptions using the SAVE EXCEPTION clause. The problem is I seem to be running into an error when trying to make the update to the driver table (the commented out code). With this in, I get the error:

ORA-01410: invalid ROWID
ORA-06512: at "CUST_MAIL_UPDATE", line 217
ORA-06512: at line 38

Can the CURRENT OF not work with the FORALL? What is my best approach here? If I use a FOR LOOP I lose my SAVE EXCEPTIONS exception handling.

The Procedure is as follows:

-- declare some object structures to hold the retrieved data
TYPE driver_rec IS RECORD (
account_no ext_driver.account_no%TYPE,
update_action ext_driver.update_action%TYPE,
customers_rowid ext_driver.customers_rowid%TYPE);
TYPE driver_recs_tt IS TABLE OF driver_rec;
-- cursor to get the records from the driver table
