If you've set the attribute's permissions to read-write, it should be fine. It could be something else, for example, that you haven't assigned the correct module role to the user role.
Hi Lee jinkyu,
Option 1: Give update security in domain model page.
Option 2: Kindly delete the CurrentIndex attribute then create new attribute as CurrentIndex
Hi Lee,
I suggest to check the access rules tab to ensure the attribute is marked read write, for the module role that is assigned to the user role that your user has.
If that doesn't work you could also try setting a breakpoint in your microflow, and checking the currentUser object to confirm the current user has the expected user role.
If this is a client side change (happening in a nanoflow on the app) then reinstalling the app might also help with any synchronization issues.
