Set Interactive Grid readonly field value by a button/link
APEX version : 24.2.0
Dear Apex experts,
There is a text box field called CONFIRM_DATE in the Interactive Grid.
This field is not manually editable, but its value can only be set by a button or link.
The set value is then saved to the database by the user using the standard Save button in the Interactive Grid.
I've noticed that the javascript model for Display Only or Read Only items doesn't allow the setValue operation.
It is easy to do in Oracle Forms, but how can I achieve this in APEX ?
