How to apply UI policy to a catalog variable attribute ?

[Honor_ Lagaza]

Hello community, 

I am building a form, and I need to make a field mandatory when another filed's attribute (active, class or any attribute of the field) have a certain value. 

How should I proceed without scripting please ? 

P.S. : It is not a condition on a form field, but on the form field attribute !

Hi @Honor_ Lagaza 

You can do the dot walk. 

Like in this example I want to user caller.VIP = True , in same manner you can do.

@Dr Atul G- LNG Hi, 

Thanks for your reply and sorry for the delay. 

My point is that the dot walking is not reachable on a form I'm building. On the form I'm designing, I create a reference field, and I want to apply a UI policy on related fields of this reference field (or field attributes). I can't access these related fields to put a condition on them and create the UI policy. Can this be done without scripting please ? 

Thanks for your time. 

Best regards, 

Hono.

Hi @Honor_ Lagaza 

Try using dot-walking like this. The “Show Related Field” option helps you perform dot-walking to reference fields.

Hi @Dr Atul G- LNG , 

Thanks for your proposal. But this works for UI policies applied to the whole table as in your sample, not for catalog UI policies built on a form... Do you get my point please ? 

Thank you
