apex tabular form icon link column

I am working with a wizard-generated Tabular Form column that needs to display an icon which launches a Javascript function and pass the row value into the function when clicked. The function launches a popUp2 window which sets the values of other fields on that row. So the row number is crucial, but it is always 0 for newly-created rows (in APEX 4.0.0.00.46). I managed to solve that problem by storing the rowNum of new rows into my Updated By column during AddRow.

What I have now is an Updated By column ("Lookup" Heading) which stores the row number of new rows, has onClick="javascript:usePopup(this);" in the Element Attributes which launches the popUp window function, and then gets any values under 2 digits wiped before submit. This fills the correct fields and submits to the table with no problem.

I can't keep using the Updated By column for this function, though. There are currently reports running on this table, so I can't add a new column to the table. I need a dummy column to display the icon, temporarily store the Row Number of newly created rows, and not mess up the MRU. It is f08, so the value of f08_0005 needs to be 0005. I tried making a null column with

select
"FUEL_USAGE_DETAIL_ID", ...   
"EXPENSE_TO_PROJECT",   
"EXPENSE_TO_TASK",   
NULL Lookup,   
"UPDATED_BY",   
"PROVIDER"  
from "#OWNER#"."FUEL_USAGE_DETAIL"

but that can't submit. I get the Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "01A949FAF0B3A91914ECACCDC9BBA9E6", item checksum = "B6ADF86455B14EF691B2AFB314926A0D".

Please help me create a null column to display this icon, store the row number of all the rows (including the brand new rows), and not mess up the MRU. If you need pictures of what I have and what I need, see my other thread: https://community.oracle.com/thread/3649771 Thank you!
