Tracking row status

Question

I have master detail setup real similar to a department employee setup. I'll use that as my example for simplicity. From the master page, user can select a button which will bring them to the associated detail row(s) page. There, the user can edit, create, delete rows. When finished, they have 2 options -- selecting OK button or selecting Cancel button. If they select the OK button, i want the changes/additions/deletions that were made to be stored temporarily until a commit is performed. However, if they choose the Cancel button, i want any changes made to these employee records undone, or reverted. I'm trying to use the framework to track the status of these rows, but it seems to come up short of the functionality i need. Here's a step by step example of the type of problem i'm having.
1) User creates a new employee record on the details page. At this point, the status of the row is STATUS_NEW.
2) User clicks OK, returning them back to the master page. The newly created row is still around.
3) User goes back in to the detail page and creates another employee record. Now, I have two employee records, both with a status of NEW. If user clicks the cancel button after creating the second employee row, what i need is for the second row only to be deleted or removed, because the first row is temporarily saved because user selected the ok button after creating it. However, the code i have behind the cancel button iterates thru all the detail (employee) records and does a refresh(Row.REFRESH_REMOVE_NEW_ROWS | Row.REFRESH_UNDO_CHANGES) to remove those rows that were just created or to undo changes made to those rows since coming in to the page. The problem with this is that the first employee record still has a status of NEW because nothing has been committed, so it gets deleted/removed along with the second row that was created. Calling postchanges() behind the OK button isn't an option because these are detail rows in a one to many relationship, so obviously there can't be an insert of a child row without the parent row being saved first. Can i use the framework and this row status stuff to accomplish what i need, or am i going to have to write a bunch of my own code to keep track of row status? Thanks.

Try this
Change this in JS
vAjaxRequest.add('AI_TEMPORARY_ITEM', pThis.value);To
vAjaxRequest.add('x01', pThis.value);In the Application Process make following changes
DECLARE
NumRec number := 0;
-- New line below. enquote_literal is to prevent SQL Injection
vTemp   varchar2(4000) := dbms_assert.enquote_literal(apex_application.g_x01);
BEGIN
--NumRec:=issue_tracking_pkg.issue_status_exists(:AI_TEMPORARY_ITEM);
NumRec:=issue_tracking_pkg.issue_status_exists(vTemp);
htp.p(NumRec);
-- htp.p(:AI_TEMPORARY_ITEM);
END;Regards,
