Problem
Occurs when, when using Change Design Info functionality to establish an alternate minimum degradation value on an Asset and adding a new Minimum Value Calculation calculator to the minimum Value Calculations dialog to calculate a new value.
The newly added calculator does not display calculation updates properly when inputs are changed.
Minimum value on the UI is not updated/refreshed, but if you View Results, you can see that the calculation did occur.
Solution
On appropriate Asset type definition, Degradation tab, when adding new Supported Calculations, set the bool on the dialogue presented to Automatically perform this calculation when the calculator is created. When this bool is set, the defined calculators are persisted as available calculators on the Asset and are ready to be used to change default design information.
Or, when you add/create the new calculator in the Change Design Info function, click OK without trying to use it, then go back in to use it.
