I have a requirement where an inputfield should be grayed-out so the user can't simply type whatever they want into the field. However, the user should still be able to change the value of the inputfield via the input help (F4). After searching around in the forums, I see that the only way to do this is to use a custom input help (as opposed to DDIC or OVS). I've done that, and it works fine when the inputfield is open. However, as soon as I set the inputfield to "Read Only", the input help button goes away.
How do I get the input help button to stay even though the field is set to "Read Only"?
