Case
We need to start a Dialog in Virtual Assistant and cancel any ongoing Skill dialog (If any)
Example
LiveChat - part of Virtual Assistant
CreateIncidentDialog - part of skill
Suppose we are in the middle of CreateIncidentDialog and the user wants to start LiveChat. We are supposed to start LiveChat and cancel current CreateIncidentDialog.
Sample Code
MainDialog.ts in Virtual Assistant
If current Dialog is a part of skill, we are starting a dialog with activity.type as EVENT for skill.
switch (gIntent) {
case 'Escalate': {
// Checking if current Dialog is a part of Skill
if (isSkill) {
const activity: Activity = innerDc.context.activity;
if ((activity.value === null || activity.value === undefined)) {
activity.value = { userState: userProfile };
};
activity.type = ActivityTypes.Event;
activity.name = "liveChat";
const skillDialogArgs: BeginSkillDialogOptions = {
activity: activity as Activity
};
await innerDc.beginDialog(EvaConfig.LUIS_DEFAULT_INTENT, skillDialogArgs);
} else {
await innerDc.cancelAllDialogs();
}
// code for starting LiveChat goes here
// .....
// .....
// .....
}
MainDialog.ts in Skill
If activity.type is EVENT and name is 'liveChat', cancel dialogs.
protected async onContinueDialog(innerDc: DialogContext): Promise<DialogTurnResult> {
try {
let activity = innerDc.context.activity;
if (innerDc.context.activity.type === ActivityTypes.Message) {
// .....
// .....
// .....
} else if (activity.type === ActivityTypes.Event) {
const ev = activity;
if (ev.name !== undefined && ev.name.trim().length > 0) {
switch (ev.name) {
case 'liveChat': {
await innerDc.cancelAllDialogs(true);
return await innerDc.endDialog();
}
}
}
}
return await super.onContinueDialog(innerDc);
} catch (e) {
console.log(`Error onContinueDialog ---> ${e} `);
return await this.hanldeException(innerDc);
}
}
Issue
The above code is not able to cancel the skill's dialog correctly. If we try to start a new dialog after the cancellation of skill dialog, it again sends an activity with activity.type as EVENT to routeStep method of MainDilaog.ts in Skill. Please find the sample code below for the same.
routeStep method of MainDialog.ts in Skill
protected async routeStep(stepContext: WaterfallStepContext): Promise<DialogTurnResult> {
console.log('skill routeStep');
if (activity.type === ActivityTypes.Message && activity.text !== undefined && activity.text.trim().length > 0) {
// .....
// .....
// .....
} else if (activity.type === ActivityTypes.Event) {
const ev = activity;
if (ev.name !== undefined && ev.name.trim().length > 0) {
switch (ev.name) {
case 'SampleAction': {
// .....
// .....
// .....
}
}
} else {
// If we try to start a new dialog, control comes here
await stepContext.context.sendActivity({
type: ActivityTypes.Trace,
text: 'An event with no name was received but not processed.'
});
}
}
} else {
await this.responder.replyWith(stepContext.context, MainResponses.responseIds.dontHavePermissionServiceNow);
await this.complete(stepContext);
}
return await stepContext.next();
}
Step to Reproduce
Step 1. Start a Dialog in Skill
Step 2. End the Dialog in the Skill and start a Dialog in VA
Step 3. Start a new Dialog
Thanks.

I am trying to develop virtual assistant using typescript . i have followed this below document
https://microsoft.github.io/botframework-solutions/tutorials/typescript/create-assistant/1_intro/
When i run npm start and test it in Botframework emulator , the bot is not responding any message.
But the Bot is opening with new user greeting adaptive card message
I have tried to edit the adaptive greeting card following this document page
https://microsoft.github.io/botframework-solutions/tutorials/typescript/customize-assistant/2_edit_your_greeting/
but eventhough the bot is not replying any message
`[11:53:22]Emulator listening on http://localhost:49963`
[11:53:22]ngrok listening on https://b2915c2d.ngrok.io
[11:53:22]ngrok traffic inspector:http://127.0.0.1:4040
[11:53:22]Will bypass ngrok for local addresses
[11:53:23]<- messageapplication/vnd.microsoft.card.adaptive
[11:53:23]POST200conversations.replyToActivity
[11:53:23]POST200directline.conversationUpdate
[11:53:23]POST200directline.conversationUpdate
expected and actual results: it should ask what is your name once connected and start conversing

first time application asking permission for the camera, if we deny the permission it won't ask again if we allow its working fine ??
var scanPage = new ZXingScannerPage();
var cameraStatus = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.Camera);
if (cameraStatus != PermissionStatus.Granted)
{
var results = await CrossPermissions.Current.RequestPermissionsAsync(new[] { Permission.Camera });
cameraStatus = results[Permission.Camera];
if (cameraStatus == PermissionStatus.Granted)
{
// Navigate to our scanner page
await Navigation.PushAsync(scanPage);
scanPage.OnScanResult += (result) =>
{
Device.BeginInvokeOnMainThread(async () =>
{
await Navigation.PopAsync();
txtbarcode.Text = result.Text;
});
};
}
else if (cameraStatus == PermissionStatus.Unknown)
{
await Navigation.PushAsync(scanPage);
scanPage.OnScanResult += (result) =>
{
Device.BeginInvokeOnMainThread(async () =>
{
await Navigation.PopAsync();
txtbarcode.Text = result.Text;
});
};
}
If we deny the camera permission, again its asks while opening camera until we allow the permission.
I wrote a demo about this.
https://github.com/851265601/CheckPermissionDemo
This a GIF of this demo.
Did you check the permission every time when you use the camera function? In this demo, when i click the button ,it will check the permission, then give the result to users, if not give the permission, it will still ask the persmission like the following code.
async void ButtonPermission_OnClicked(object sender, EventArgs e)
{
if (busy)
return;
busy = true;
((Button)sender).IsEnabled = false;
var status = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.Camera);
await DisplayAlert("Pre - Results", status.ToString(), "OK");
if (status != PermissionStatus.Granted)
{
status = await Utils.CheckPermissions(Permission.Camera);
await DisplayAlert("Results", status.ToString(), "OK");
}
busy = false;
((Button)sender).IsEnabled = true;
}
}
When DisplayAlert was appear, it are used MainApplication for different life cycle

I'm new in Bot framework and I face this issue:
I want to move from dialog to another dialog, the callback function is working for context.Call but not for context.Forward?
I try multiple solutions such as put this.CallbackFunctionName but it dosen't work.
Here is my code for call new dialog:
switch (submitType)
{
case "alarm":
context.Call(new AlarmDialog(), ResumeAfterAlarmDialog);
context.Done(true);
return;
case "game":
await context.Forward(new AlarmDialog(), ResumeAfterAlarmDialog, value, CancellationToken.None);
return;
}
And here the method that I call:
private async Task ResumeAfterAlarmDialog(IDialogContext context, IAwaitable<object> result)
{
await context.PostAsync($"You are finish the alarm dialog");
context.Wait(this.MessageReceivedAsync);
}
And this is the error that I have for the context.Forward:
cannot use a method group as an argument to a dynamically dispatched operation.Did you intend to invoke the method?
Here the full implementation of the class:
namespace CardEx.Dialogs
{
[Serializable]
public class RootDialog : IDialog<object>
{
public Task StartAsync(IDialogContext context)
{
context.Wait(MessageReceivedAsync);
return Task.CompletedTask;
}
private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
{
var activity = await result as Activity;
if (activity.Value != null)
{
// Got an Action Submit
dynamic value = activity.Value;
string submitType = value.Type.ToString();
switch (submitType)
{
case "alarm":
context.Call(new AlarmDialog(), ResumeAfterAlarmDialog);
return;
case "alarm2":
await context.Forward(new AlarmDialog(), ResumeAfterAlarmDialog, value, CancellationToken.None);
return;
}
}
AdaptiveCard aCard = new AdaptiveCard()
{
Body = new List<AdaptiveElement>()
{
new AdaptiveTextBlock()

Weight = AdaptiveTextWeight.Bolder,
Size = AdaptiveTextSize.Large
},
new AdaptiveTextBlock() { Text = "Please choose one of the following:" },
},
Actions = new List<AdaptiveAction>()
{
new AdaptiveSubmitAction()
{
Title = "Set an alarm",
DataJson = "{ \"Type\": \"alarm\" }"
},
new AdaptiveSubmitAction()
{
Title = "Play a game",
DataJson = "{ \"Type\": \"game\" }"
}
}
};
Attachment attachment = new Attachment()
{
ContentType = AdaptiveCard.ContentType,
Content = aCard
};
var reply = context.MakeMessage();
reply.Attachments.Add(attachment);
await context.PostAsync(reply, CancellationToken.None);
context.Wait(MessageReceivedAsync);
}
private async Task ResumeAfterAlarmDialog(IDialogContext context, IAwaitable<object> result)
{
await context.PostAsync($"You are finish the alarm dialog");
context.Wait(this.MessageReceivedAsync);
}
}
}
Thank you.
cannot use a method group as an argument to a dynamically dispatched operation.Did you intend to invoke the method?
the parameter value used in context.Forward is a dynamic type, which raised this issue.
Please try following code:
await context.Forward(new TestDialog(), ResumeAfterAlarmDialog, (object)value, CancellationToken.None);
