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.
