Correct. By default, any variable will refresh when a referenced variable changes. Even when NOT wrapped into a a!refreshVariable().

I don't need to worry about a!refreshVariable().

The SaveInto mentioned previously solves the issue for me.

To see what a!refreshVariable() is doing, just remove it and refer the direct value, and you will understand how it works.

To shed some more light ...

refreshOnReferencedVarChange - parameter doing the trick here. It's set as true by default and hence the local variables are getting refreshed on ReferencedVarChange.

refreshOnReferencedVarChange (Boolean): When true, the value of this local variable will be refreshed each time the value of any variable it references within the value parameter is updated. To refresh the local variable when another variable that is not used within value changes, use refreshOnVarChange. Default: true.

The refreshVariable doesn't seem to do anything in this instance.

However, the saveInto for the radioButtonField works as expected.

Thanks,

pete

If you want to reset ri!selectedSate to null on change of radio selection, here is the code for that.

a!radioButtonField(
label: "Country",
labelPosition: "ABOVE",
choiceLabels: local!countries,
choiceValues: local!countries,
value: { local!selectedCountry },
saveInto: { local!selectedCountry, a!save(ri!selectedSate, null) },
choiceLayout: "COMPACT",
choiceStyle: "STANDARD",
validations: {})

Also you may use following to refresh local variable when the referenced variable changes.

a!localVariables(
  local!countries: rule!PT_GetAvailableCountries(),
  local!selectedCountry: a!refreshVariable(value: local!countries),
  local!states: a!refreshVariable(value: rule!PT_GetStateByCountry(local!selectedCountry)),
  a!formLayout(
    label: "Create Customer",
    contents: {
      a!columnsLayout(
