Chat Module was disabled and disappeared after upgraded to v8.2 #7437 | Support Center | ABP Commercial

Hi ABP Team, I have a problem with Chat module after upgraded to v8.2 and use new application template Blazor Web App. My previous app I used Blazor Wasm template as the main solution in this main solution I installed Chat module. I have developed another module called Common, in this module I have added a Notification icon to toolbar follow the guideline from this: https://docs.abp.io/en/abp/latest/UI/Blazor/Toolbars, and I use SignalR to realtime update notification to show on this icon.. Then I integrated this module to Main Application, everything are ok. Now I'd like to use new application template in v8.2: Blazor Web App so I created a new Main Solution with new template then I integrated Common module as I have done before but when run the Main Solution the Chat icon on Toolbar show during page loading but was disappeared after Common module loaded completely, and on the toolbar only see the Notification icon but didn't see Chat icon. I come to Setting to check the Chat feature was also disappeared here. During loading page at beginning still can see Chat icon:
But after completing loading (included Common module) Chat was disappeared, only see the Notification I have implemented in Common module: Go to Setting there is no Chat feature there:

Thanks, Dharma Han Nguyen

Hi,

This is because the Blazor webapp has two runtimes(blazor server and webassembly)

You need to add the Volo.Chat.Blazor.WebAssembly to the WebApp.client and add the Volo.Chat.Blazor.Server to the WebApp project

Hi, I have done as you recommended but another error happened, It is quite similar to issue of getting access token I asked you yesterday on another topic: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Cannot provide a value for property 'AccessTokenProvider' on type 'Volo.Chat.Blazor.WebAssembly.Components.BlazorMessagesToolbarItem'.

Hi,

I will fixed it in the next patch version You can try this:

[ExposeServices(typeof(MessagesToolbarItem))]
public class BlazorMessagesToolbarItem : MessagesToolbarItem
{
    [Inject]
    protected IAbpAccessTokenProvider AccessTokenProvider { get; set; }

    [Inject]
    protected IOptions<ChatBlazorWebAssemblyOptions> ChatBlazorWebAssemblyOptions { get; set; }
    
    [Inject]
    protected IOptions<AbpRemoteServiceOptions> AbpRemoteServiceOptions { get; set; }

    protected async override Task SetChatHubConnectionAsync()
    {
        var token = await AccessTokenProvider.GetTokenAsync();

        var signalrUrl = ChatBlazorWebAssemblyOptions.Value.SignalrUrl ?? AbpRemoteServiceOptions.Value.RemoteServices.Default.BaseUrl;
        
        HubConnection = new HubConnectionBuilder()
            .WithUrl(signalrUrl.EnsureEndsWith('/') + "signalr-hubs/chat", options =>
            {
                if(!token.IsNullOrWhiteSpace())
                {
                    options.AccessTokenProvider = () => Task.FromResult(token);
                }
                
            })
            .Build();
    }
}

I added your code and got other error, so I think I will wait for your patch of this version. In additional, I have another question, how can I change the footer info before login, I can custom MainFooterComponent.razor in Blazor.Client to change but this information only update after login and loading Blazor Web Assembly. Thanks
