I have 2 regions, one for Parameters which should not impact on database when values changed, another is a Form updateable IG which is showing data based on parameters in Param_Region. When I am Selecting only Location and want to leave the Form or switch the form from side menu, it is showing dialog for Changes may not be saved.
There is a property on Page level ( Navigation -> Warn on Unsaved Changes [Yes] [No] ), if I set it to No this will not warn even if user made some changes in updateable IG... this option not available on Region level, how I can have it on Region level so it cannot show the dialog for changes in Param Region and show only for the Region Updateable IG ?

if JavaScript involved, please help with code as I don't know JS ( visiting https://www.w3schools.com/ now to have some working knowledge to use with Oracle Apex )
