I found the issue.. I need to stop the hub and restart to allow the event handlers to be registered.

But when I declare a new hub context at the server side, and use it to broadcast the event data. _hubContext = GlobalHost.ConnectionManager.GetHubContext<AbpCommonHub>(); _hubContext.Clients.All.sendEventData(eventData.Entry); The hub context is differentfrom the context used by abp's signalr hub context so the event is not associated to the event handler at client side. <ins>Could you advice if there is a way for me to use the same hub context with abp's signalr?</ins>

For abp's Chat and Notification functions, I saw messges are starting from **hub.server.sendMessage(message), and then in SendMessage method, you just need to use 'Clients.All.getMessage(anotherMessage)' because the hub context is already there and you are always using the same hub context.

[HubName("shoppingCartHub")]
public class ShoppingCartHandler : AbpCommonHub, IEventHandler<EventData>
{
    private IHubContext _hubContext;

    public ShoppingCartHandler(IOnlineClientManager onlineClientManager, IClientInfoProvider clientInfoProvider) : base(onlineClientManager, clientInfoProvider)
    {
        _hubContext = GlobalHost.ConnectionManager.GetHubContext<AbpCommonHub>();
    }

    public void HandleEvent(EventData eventData)
    {
        _hubContext.Clients.All.sendEventData(eventData.Entry);
    }
}

I'm using EventBus.Trigger to pass the message from the ShoppingCartService application service to the shoppingCartHub, and in the HandleEvent method I called SignalR dynamic method sendEventData.

public class ShoppingCartService : MyProjectAppServiceBase, IShoppingCartService{
       ...
      public async Task EditCartData(ShoppingCartInput shoppingCartInput){
               ...
              EventBus.Trigger(new EventData() { ItemId = itemId});
      }
    }

According to the comment in following page, I changed my client side a little: <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/issues/1891">https://github.com/aspnetboilerplate/as ... ssues/1891</a>

I've been having this issue too. I think I may have narrowed it down to abp.signalr.js connecting to the server before the client side events have been established. It seems you need to call $.connection.hub.start() after you have set up your events. I'm guessing it is so that it can do some bindings.

If I set abp.signalr.autoConnect = false and then manually call abp.signalr.connect() at the end of my controller, all clients start receiving calls from the server as expected.

Updated Client Side

abp.signalr = abp.signalr || {};
        abp.signalr.autoConnect = false;

        $.connection.hub.url = abp.signalr.url || '/signalr';
        $.connection.hub.logging = true;

        var shoppingCartHub= $.connection.shoppingCartHub;
        shoppingCartHub.client.sendEventData= onEntryCreatedorUpdated;

        abp.signalr.connect();
        console.log("abp.signalr after connect", abp.signalr);

It's still not working... One thing I noticed from console.log("abp.signalr after connect", abp.signalr); is shoppingCartHub is not in the Connection List and is in the Proxies list. Here is the snapshot: [attachment=0:2fz49oxu]2018-05-23_22-30-34.jpg[/attachment:2fz49oxu] Is that the reason why the callback function is not reached?

I've registered the shoppingCartHub on the same site as ChatHub: localhost:6240/signalr. It's successful registered as console.log("shoppingCartHub", shoppingCartHub ) returns me the hub object at client side and I could see a message in the console: SignalR: Triggering client hub event 'sendEventData' on hub 'AbpCommonHub'. But not sure why the callback function was not get called. Could you help me take a look where I did incorrectly?

Server Side. Is it correct to use AbpCommonHub instead of ShoppingCartHandler in the return type of _hubContext ? _hubContext = GlobalHost.ConnectionManager.GetHubContext<AbpCommonHub>();?

[HubName("shoppingCartHub")]
public class ShoppingCartHandler : AbpCommonHub, IEventHandler<EventData>
{
    private IHubContext _hubContext;

    public ShoppingCartHandler(IOnlineClientManager onlineClientManager, IClientInfoProvider clientInfoProvider) : base(onlineClientManager, clientInfoProvider)
    {
        _hubContext = GlobalHost.ConnectionManager.GetHubContext<AbpCommonHub>();
    }

    public void HandleEvent(EventData eventData)
    {
        _hubContext.Clients.All.sendEventData(eventData.Entry);
    }
}

Client Side:

$.connection.hub.url = abp.signalr.url || '/signalr';
        $.connection.hub.logging = true;
        var shoppingCartHub = $.connection.shoppingCartHub;
        console.log("shoppingCartHub", shoppingCartHub );     //this line could run.
        shoppingCartHub.on("sendEventData", function (message) { console.log("called inside event", message);})

        $.connection.hub.start().done(function () {
            console.log('ShoppingCart Hub has started');   //this line could run.
        });
        $.connection.hub.error(function (err) {
            console.log("ShoppingCart Hub ERROR : " + err);
        });

Autogenerated proxy: Seems it's only contains handleEvent method.

proxies['shoppingCartHub'] = this.createHubProxy('shoppingCartHub'); 
        proxies['shoppingCartHub'].client = { };
        proxies['shoppingCartHub'].server = {
                handleEvent function (eventData) {
                return proxies['shoppingCartHub'].invoke.apply(proxies['shoppingCartHub'], $.merge(["HandleEvent"], $.makeArray(arguments)));
             },

            register: function () {
                return proxies['shoppingCartHub'].invoke.apply(proxies['shoppingCartHub'], $.merge(["Register"], $.makeArray(arguments)));
             }
        };

Gotcha, thank you!

<cite>ismcagdas: </cite> Hi @OriAssurant ,

1. Yes, you can but you need to reference Microsoft.AspNet.SignalR in the Application project. Yes, you need to register it.

I couldn't understand the other two questions, sorry. Why don't you use a similar way we did for Chat feature. You can define a ShoppingCartHub similar to <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero-core/blob/dev/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Web.Core/Chat/SignalR/ChatHub.cs">https://github.com/aspnetzero/aspnet-ze ... ChatHub.cs</a>.

On the client side, when a user adds an item to cart, instead of calling the app service, you need to communicate with the ShoppingCartHub. Then it will notify all open browsers (including the one which users is shopping on) to add this new item to user's cart.

You can take a look at how we send chat message to another user.

Thank you very much, ismcagdas. Let me try with the ChatHub way:)

This is awesome. Let me try it now! Thank you so much Aaron.

Thanks for your help, we figured it out:

_context.DisableAllFilters();

Sure, thank you Aaron. Here is the configuration.cs for tenant databases:

namespace x.y.PortalDBOneMigrations
{
    public sealed class Configuration : DbMigrationsConfiguration<EntityFramework.PortalDbOneContext>, IMultiTenantSeed
    {
        public AbpTenantBase Tenant { get; set; }

        public Configuration()
        {
        }

        protected override void Seed(PortalDbOneContext context)
        {
            context.EntityChangeEventHelper = NullEntityChangeEventHelper.Instance;
            context.EventBus = NullEventBus.Instance;

           //seeding data for tenant id 2
            new UserRolePermissionTenantCreator(context, 2).CreateUserRolePermission();  
        }
    }
}

Hmm.. sorry forgot to mention I'm using MVC5.* + AngularJS. Seems IgnoreQueryFilters is not available in this version? I got this error:

IDbSet<User>' does not contain a definition for 'IgnoreQueryFilters' and no extension method 'IgnoreQueryFilters' accepting a first argument of type 'IDbSet<User>' could be found (are you missing a using directive or an assembly reference?)

This is how I intatiate the mapping call:

public string ManageOrder(DtoInputEntity inputEntity) { //this works Entity dto = new Entity(); dto = inputEntity.MapTo<Entity >();

        //this does not
         EntityLine dtoLine = new EntityLine();
          dtoLine = inputEntity.MapTo<EntityLine >();

}

is it because Shipment Number is being assigned against both Entity and EntityLine?
