How to fix Overload Resolution Ambiguity in Kotlin (no lambda)?

I am having Overload Resolution Ambiguity error in this line:

`departureHourChoice!!.selectionModel.select(currentHourIndex)`

For Reference:

- `departureHourChoice` is a `ChoiceBox<Int>`, which is from `java.scene.control`

- `currentHourIndex` is an `Int`

- The Overload Resolution Ambiguity happens in the `.select()` method; It is overloaded and can accept two kinds of parameters: `(T obj)` or `(int index)`.

- The `.select()` method allows for an item in a `ChoiceBox` to be selected, and you can determine which one can be selected by referencing to that item or to it's index. In this case, I want it to be selected by Index (`int`).

How would one resolve the Overload Resolution Ambiguity?


[1]:

Try casting to `Int`:

departureHourChoice!!.selectionModel.select(currentHourIndex as Int)

It seems that you are hit by [this bug](

) as a workaround you can :

- box the `currentHourIndex`:

lateinit var departureHourChoice: ChoiceBox<Int>
...
val currentHourIndex = 1
departureHourChoice.selectionModel.select(currentHourIndex as Int?)

- or change declaration of `ChoiceBox` to use `java.lang.Integer` instead of Kotlin's `Int`:

lateinit var departureHourChoice: ChoiceBox<java.lang.Integer>
...
val currentHourIndex = 1
departureHourChoice.selectionModel.select(currentHourIndex)

The solution for me in similar situation is to define in your import for example:
import kotlin.math.sqrt as kotsqrt

then use as:
val a = kotsqrt(2.3)
