Unable to reset hidden property value in constellation using form refresh

I have property A, property B. When property A changes i’m triggering form refresh DT, In that DT if property A is < 1 i’m setting property B as null & property B is hidden when property A is < 1.

Property B is getting hidden but in the backend the value is not clearing.

If you hide something from the View then it is not available in the DX API payload, so it won’t update. This is a security feature of Constellation - you can only update fields you can see in the View.

I would recommend you do this is post-processing of the assignment.

In Infinity '26, this changes a little, you have the ability to specify fields that are not editable in the form, that you are allowed update.

Okay but my requirement is to set property B as 0 & hide property B when property A is < 1.

Instead of hiding property B i tried workaround like disabling or making the field read only.

But none of them either worked. Can u give a workaround which could hide the field and also update it in the same screen if feasible.

Hide property B when A < 0, in post processing of the flow action set it as null?
