How to Apply Field Validation on Classic UI Detail in Freedom UI Editable Detail

Hello Creatio Community,

I am currently working on a page in Freedom UI which contains a detail. The detail's object resides in Classic UI. I need to apply field validation on this detail while performing inline editing within the Freedom UI.

Here's a brief overview of what I'm trying to achieve:

1. The main page is in Freedom UI.
2. The detail object is in Classic UI.

3. I need to implement field validation on the detail during inline editing.

    

I've attempted a few approaches, but none seem to provide the desired results. Has anyone faced a similar challenge or can provide guidance on how to achieve this functionality?

Any help or pointers would be greatly appreciated.

Thank you!
