Iterating over ScriptableObject.

[Andrei Vinogradov]

Hello everyone. I have an issue and could not find out how to solve it.

If I define ScriptableObject like this (samples are in Kotlin):

class JavaWrapper() : ScriptableObject() {
    init {
        defineProperty("name", "John", PERMANENT)
        defineProperty("surname", "Doe", PERMANENT)
    }

    override fun getClassName(): String = javaClass.name
}

then iterating over it would be successfull and calling

for (var property in JavaWrapper) { print(name); }

will result with "name surname" as expected.

But if I define same ScriptableObject in another way:

class JavaWrapper() : ScriptableObject() {
    override fun getClassName(): String = javaClass.name

    override fun get(name: String, start: Scriptable): Any {
        return when (name) {
            "name" -> "John"
            "surname" -> "Doe"
            else -> Scriptable.NOT_FOUND
        }
    }
}

iteration returns nothing. 

How could I modify second implementation to get iteration work successful? Sorry if my question is stupid - i'm new to Rhino.

Hi,

The `defineProperty()` method does much more than making

`get()` return passed value; you'll need to additionally override

at least `getIds()` and `has()` for the loop to work:

```

class Wrapper : ScriptableObject() {

    override fun getClassName(): String = javaClass.name

    override fun get(name: String, start: Scriptable): Any {

        return when (name) {

            "name" -> "John"

            "surname" -> "Doe"

            else -> Scriptable.NOT_FOUND

        }

    }

    override fun has(name: String, start: Scriptable): Boolean {

        return name == "name" || name == "surname"

    }

    override fun getIds(): Array<Any> {

        return arrayOf("name", "surname")

    }

}

```

I don't know your goal here (it looks like a http://xyproblem.info/

type of question), so could be that overriding/reimplementing

parts of `ScriptableObject` isn't the best way to achieve it.

Best,

Ivan
