I have a requirement in Constellation where:

• There is a radio button with two options: Reward Points and US Dollars.
• If the user selects Reward Points, the US Dollar field should auto-calculate based on the reward points and remain read-only.
• If the user selects US Dollars, the field should be editable so the user can enter a value.

I implemented this using an OnChange Data Transform on the Reward Points field to set the US Dollar value. It works initially, but when I change any other property in the view, the US Dollar field refreshes and resets to 0.

Question:

• How can I prevent the calculated value from resetting after a view refresh in Constellation?
