Read only / Hide Control 15.3.0.0

Hi,

I am having hard time figuring it out on why ‘Field Read Only Field’ user property is not working. I tried on BC classes: CSSBusComp , CSSBCBase. No luck. Can you please try from your end.

Example: For one-way trip, we want to Hide/RO ‘Return Date’ field. (Note: We are not looking for Toggle applet as a solution here)

Things I tried:

Field Read Only Field – user Property

Read Only – user property

Hide Control – User Property

Hide Control – Browserscript (for some reason, it’s not triggering for CheckBox HTML Type)

Question:

Can I have "EnableOpenUI = True" and "HighInteractivity             = TRUE". If yes, how does Browser Scripts work?
