Unable to modify conversationData, userStorage values in Kotlin

[pawelcala]

conversationData and userStorage are immutable values and cannot be changed using kotlin.
For now there is no option to modify this! One of possible solution is to override getResponseBuilder in DialogflowApp and construct own ResponseBuilder with custom data BUT ResponseBuilder is internal class.
Someone already noticed that in other task few months ago and you didn't fixed it yet.
Please fix this!

This is the same as #17, where you can clone the object to a mutable implementation.

As said in #17 userStorage works fine when cloned.

But conversationData doesn't works.

The conversationData is overrided in ResponseSerializer.kt

actions-on-google-java/src/main/kotlin/com/google/actions/api/impl/io/ResponseSerializer.kt

Line 94 in 5e2c7c9

contexts?.forEach { setContext(it, webhookResponse) }

You should put it before line 86

As workaround you can try to access and modify conversationData trough context

ActionContext context = request.getContext(request.getSessionId() + "/contexts/" + "_actions_on_google");
String serializedData = (String) context.getParameters().get("data");
Type empMapType = new TypeToken<Map<String, Object>>() {}.getType();
Map<String, Object> conversationData = new Gson().fromJson(serializedData, empMapType);
...
conversationData.put("test", test);
responseContext.getParameters().put("data", conversationData);

Edit:
The workaround was a bad idea, once the conversationData has been set it can't be parse in the next request due to a class cast exception (String <=> LinkedTreeMap).

actions-on-google-java/src/main/kotlin/com/google/actions/api/impl/DialogflowRequest.kt

Line 63 in 5e2c7c9

val serializedData = parameters?.get("data") as String

The same thing seems to work for conversation data in Kotlin

val sessionData = mutableMapOf<String, Any>()
sessionData.putAll(aogRequest.conversationData)

val headquarters = sessionData["headquarters"] as MutableList<String>
assertEquals("google1", headquarters[0])
headquarters[0] = "google2"

sessionData["headquarters"] = headquarters
val responseBuilder =
        ResponseBuilder(usesDialogflow = false, conversationData = sessionData)

val aogResponse = responseBuilder.build()
val jsonOutput = aogResponse.toJson()

[cbeaujoin]

Have you noticed that conversationData is overided by the context: [sessionId]/contexts/_actions_on_google

[Fleker]

When using Dialogflow?

When using Dialogflow?

Yes
