Tabular form with uneditable apex_item.text column

Question

When I use the following query for my Tabular Form I have the AGE column uneditable
select
"ID",
"ID" ID_DISPLAY,
apex_item.text(44,"AGE") as "AGE"
from "#OWNER#"."SAS_TEST"
I changed the AGE column type to Standard Report Column but still the column values are not able to update the values.
The column will show the HTML input and view the correct values from the table but you can not update the column.
I have apex 4.0.2

I found the solution. You must have both the original column in your sql (as hidden type), and you must add the APEX_ITEM.TEXT with an alias different than the true db column name.
In order to set the hidden real column values after submitting the page, add the page process pl/sql below. Of course you need to find the g_fxx number by looking at your page source. This will transfer the values from one pl/sql table to the other which is mapped in the MRU process.
On Submit - Before Computations and Validations
BEGIN
-- Database Column Name: DEFAULT_VALUE
-- Set the hidden DEFAULT_VALUE field for all visible records to null
-- Note: g_f19 maps to the hidden DEFAULT_VALUE column
-- g_f30 maps to the visible DEFAULT_VALUE_ADMIN column
FOR ii IN 1 .. APEX_Application.g_f19.COUNT
LOOP
APEX_Application.g_f19(ii) := APEX_Application.g_f30(ii);
END LOOP;
END;
