ResumeAfter method is already called without calling context.done in the next dialog - botframework

Question

I have implemented a structure where a QnA dialog is first started. If the QnA Dialog cannot solve the problem then it starts a Luis Dialog which has some main functionalities defined. Based on those main functionalities I start specific dialogs that can solve the problem.
My problem is that when I try to start LuisDialog from QnAMaker, it starts another LuisDialog to for conversation, That dialog doesn't stop on with wait method and automatically calls ResumeAfter method immediately after executing.
QnADialog:
protected override async Task RespondFromQnAMakerResultAsync(IDialogContext context, IMessageActivity message, QnAMakerResults results)
{
if (results == null || results.Answers.Count==0 || !IsConfidentAnswer(results) || results.Answers.FirstOrDefault().Score<0.75) {
await context.Forward(new MainLuisDialog(), MessageReceived, context.Activity.AsMessageActivity(), CancellationToken.None);
}
}
First Luis Dialog:
[LuisIntent(ErrorFileLink)]
public async Task ErrorFileLinkIntentHandler(IDialogContext context, LuisResult result) {
await context.Forward(new ErrorFileLinkDialog(), CallBackHandler, context.Activity.AsMessageActivity(), CancellationToken.None);
}
private async Task CallBackHandler(IDialogContext context, IAwaitable<object> result)
{
try {
var returnedResult = await result;
if (returnedResult as string == "done")
context.Done(false);
}
catch (Exception e) {
}
}
2nd Luis Dialog:
[LuisIntent(MainAppIntent)]
public async Task MainAppIntentHandler(IDialogContext context, LuisResult result)
{
if(context.GetPrivateConversationData<SyncIssueStates>(CurrentDialogState) == SyncIssueStates.ExpectingSyncCompleteMessage)
{
await context.PostAsync(Utility.GetResourceString("SYNC_ISSUE_PLEASE_WAIT_SYNC_COMPELTE"));
context.Wait(MessageReceived);
return;
}
await context.PostAsync(Utility.GetResourceString("SYNC_ISSUE_GET_ERROR_MESSAGE"));
context.SetPrivateConversationData(CurrentDialogState, SyncIssueStates.ExpectingErrorMessage);
context.Wait(MessageReceived);
}
CallBackHandler Method in First Luis Dialog is called right after Forward is executed.

I think this behavior is due to the fact that the QnAMakerDialog calls context.Done(true); inside the DefaultWaitNextMessageAsync method. ref: https://github.com/Microsoft/BotBuilder-CognitiveServices/blob/master/CSharp/Library/QnAMaker/QnAMaker/QnAMakerDialog.cs#L203
Try overriding the DefaultWaitNextMessageAsync method instead:
protected override async Task DefaultWaitNextMessageAsync(IDialogContext context, IMessageActivity message, QnAMakerResults results)
{
if (results == null || results.Answers.Count == 0 || !IsConfidentAnswer(results) || results.Answers.FirstOrDefault().Score < 0.75)
{
await context.Forward(new FirstDialog(), AfterForward, context.Activity.AsMessageActivity(), CancellationToken.None);
context.Wait(base.MessageReceivedAsync);
}
else
{
await base.DefaultWaitNextMessageAsync(context, message, results);
}
}
