I have a presenter (proxy code split) with method foo(). An application was deployed and started. I changed the method signature to foo(int id), stopped the server, deployed the new version of the application and started the server again. When the page with presenter was opened an error occurred because the failed file (generated by gwt compiler and loaded later in situation when proxy code split was used) couldn't be loaded (the names were changed after new compile).
Does anybody know how can I register some code to the situation when a proxy presenter couldn't be loaded?
Kind regards
Sebastian
Problem solved. There are two presenters: Main and NotMain :) NotMain has implemented AsyncCallFailHandler while Main should.

I've created a Blazor Component within a full Blazor project and all works well.
However, when I move this component to it's own Razor Class Library project, I am now getting an error that I cannot use JSInterop until a connection with the server is made. I am running my code in the OnAfterRenderAsync() method.
I had to alter the code a little when I made the change.
In a full Blazor project, JSInterop is provided for you with DI in the Startup class. But this is not the case with a calss library.
So instead of "#inject JSInterop js" in the page, I had to set it up like this -
private IJSRuntime js { get; set; }
protected override void OnInitialized()
{
js = ScopedServices.GetRequiredService<IJSRuntime>();
}
From the sketchy details available on the web, I'm assuming this gets the service from the Parent project.
Using debugging, I can see that js is NOT null. It does seem to have been set to a valid object.
Can anyone point me in the right direction?
The server pre-renders, so your code will run before there is a client connection to the server. When rendering in OnAfterRenderAsync you should only use IJSRuntime when the firstRender parameter is true, or any point after that, but never before.
Found the solution to my problem and it has rendered my initial question irrelevant.
When I copied my component to it's own class library project, it would not compile. It gave me an error on the line #inject JSInterop js.
This led me to believe that it didn't know how to inject this as it is not set during the Startup of the project, as it is in a Blazor app.
So I cobbled together the code to get a reference via ScopedServices.GetRequiredService().
This did create an object but did not have _clientProxy set which contains the connection to the server.
So digging round I managed to find a complete component library example project at BlazorHelp Website
This did have the JSInterop injected in the Blazor file. So I reverted my code back to the original code that worked in the full project and tried to compile. It gave me the same error. So I deleted the #inject JSInterop js line and typed it in again.
IT RECOGNIZED IT!!!
It still failed to compile, not recognizing a custom type (Pivot) and asking whether I had included a reference to it.
[CascadingParameter] public Pivot OwnerPivot { get; set; }
I deleted the word Pivot and retyped it and, voila, it compiled.
So it looks like there some sort of error in VS2019 or the razor compiler, where deleting code in the source file and re-entering caused it to recognize and compile.
I have a micronaut API like this:
#Get("/")
List<Club> listClubs()
#Get("/{id}")
Club show(Long id)
In my unit test, when I invoke the show method, the listClubs() method is actually getting invoked, instead.
Why is this happening?
Details:
Thinking that my URL mappings must be wrong, I started debugging into Netty to try to understand how the framework constructs URLs.
In HttpClientIntroductionAdvice, the context shows the API method like this:
Club show(Long param0)
The interceptor is setting param0 in the parameter map, which doesn't match the actual parameter name of my method. When the URI template is expanded, this causes the ID to get dropped (thus the URI becomes / instead of /1).
I am trying to follow this example:
https://github.com/alvarosanchez/micronaut-workshop/tree/master/ex02/solution/clubs
There is one important different in my project, which is that the endpoint is set at "/club" instead of at "/":
#Controller("/club")
#Client("/club")
I am using a diff tool to compare my project to the sample, but I am struggling to find any other difference (besides package name changes).
Why is this happening? What should I be looking for?
Thanks
Update:
Tested the target endpoint with the browser - looks fine.
Gradle clean does not resolve the issue.
I switched from debugging the Application class with IntelliJ to using "gradlew run" and in the process, I made a change to build.gradle (adding JVM properties pass-through from the gradle CLI). I also played with enabling/disabling the annotation processor in the IDE.
(note: In the previous project, I enabled annotation processing as soon as I imported into the IDE. On this project, I didn't enable it until I started having issues.)
I think the build.gradle alteration caused the problem to go away. Since the issue shows up unreliably, it's hard to tell for certain if this is the change that caused it to be fixed.
I have a WebApp on Azure that uses a dll. This library needs Interop libraries x86 and x64.
Sometimes, at the restart of the App (I suppose), the App fails due to an exception:
System.EntryPointNotFoundException: Unable to find an entry point named 'sqlite3_config' in DLL 'SQLite.Interop.dll'. at System.Data.SQLite.UnsafeNativeMethods.sqlite3_config_none(SQLiteConfigOpsEnum op) at System.Data.SQLite.SQLite3.StaticIsInitialized() at System.Data.SQLite.SQLiteLog.Initialize() at System.Data.SQLite.SQLiteConnection..ctor(String connectionString, Boolean parseViaFramework) at T_Dox.WebService.SQLiteDb.CreateConnection() at WebService.CeDb.Connect()
The SQLite used is the SQLCipher's one.
What am I missing here? I don't understand why the app stops working suddenly even if I don't make any changes.
The App is a Web Service (.asmx file) that uses a data access layer to perform some business logic.
It was under a web site project, then we moved it into another project, a webapi\mvc project.
The routing bypasses this extension, so it works as before, a simple web service call.
The called web method initializes a business class loaded from another .net library (a VB.Net library).
Inside, this class uses a wrapper to a sqlConnection, in this case the SQLiteConnection.
In its constructor it starts an SQLiteConnection, and normally it works.
Then it performs some CRUD operations ...
So I can represent the operation this way:
[WebService(Namespace = "...")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class SampleService : System.Web.Services.WebService
{
[WebMethod]
public ServerInfo Test()
{
var sampleBusinessClass = new SampleBusinessCLass();
sampleBusinessClass.DoSomething();
using(var connection = new SQLiteConnection()) //the constructor is the parameterless one
{
//...
}
}
}
And the stack will be this (this is not the real one):
System.EntryPointNotFoundException: Unable to find an entry point named 'sqlite3_config' in DLL 'SQLite.Interop.dll'.
at System.Data.SQLite.UnsafeNativeMethods.sqlite3_config_none(SQLiteConfigOpsEnum op)
at System.Data.SQLite.SQLite3.StaticIsInitialized()
at System.Data.SQLite.SQLiteLog.Initialize()
at System.Data.SQLite.SQLiteConnection..ctor(String connectionString, Boolean parseViaFramework)
at xxx.WebService.SampleService.Test()
It always works, but sometimes it starts to launch this error until the stop and start of the web application on iss (in our case: Azure).
Inspecting the System.Data.SQlite.dll I can clearly see the entry point and actually it always passes this internal code (no conditions that can bypass this part) and it generally works.
The System.Data.SQlite.dll (1.0.96.0 version) is provided by SqlCypher product. I think it is the original System.Data.SQLite one because at first sight I can see the same assembly manifest and content.
The interop System.Data.SQLite uses is probably modified by SqlCypher team to give their features.
To avoid possible issues we put the interop in the path /bin/x64, then we compile our web app ONLY in x64 and it runs on a x64 environment.
I have an MVC5 project that is doing OwinStartup, and I'm using Ninject.MVC5, Ninject.Web.Common.OwinHost, etc.
I have NinjectWebCommon bootstrapping DI and things were working just fine. Until I started playing with the identity code.
I need to issue a password reset token, which requires a DataProtectionProvider. No problem, the ApplicationUserManager wires that up in the Create method, which is bound to the OwinContext during startup in Startup.Auth.cs:
public void ConfigureAuth(IAppBuilder app)
{
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
...
}
In my NinjectWebCommon I have the following registrations:
kernel.Bind<IDataContext>()
.ToMethod(ctx => HttpContext.Current.GetOwinContext().Get<ApplicationDbContext>())
.InRequestScope();
kernel.Bind<IApplicationUserManager>()
.ToMethod(ctx => HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>())
.InRequestScope();
The problem I'm having is that the token isn't being issued. Why isn't that what my question is about? Well, if I get an instance of the ApplicationUserManager using the Create myself and use that, things work flawlessly.
Next on my plate a reported user creation bug. Hyphens aren't working in usernames. In that same ApplicationUserManager.Create method, is the UserValidator code that's overriding the default AllowOnlyAlphanumericUserNames value.
Again, if I use a self created dependency, it works as expected. This seems to indicate Ninject's injected dependency isn't using the ApplicationUserManager.Create'd version.
I'm guessing this has to do with the call to: HttpContext.Current.GetOwinContext??
Is there something I need to do in order to inject something that relies on the owin context or something else I need to do while registering my resolver?
I've seen other questions here showing UseNinjectMiddleware and UseNinjectWebApi. I tried that approach, but didn't have any luck, nothing was being injected in...
Any assistance is greatly appreciated!
Im getting the following error when I run the coded UI application:
An exception of type 'Microsoft.VisualStudio.TestTools.UITest.Extension.FailedToPerformActionOnHiddenControlException' occurred in Microsoft.VisualStudio.TestTools.UITesting.dll but was not handled in user code
This exception arises in the Mouse.Click() function in the below code.
public static void DestinationMaster()
{
Mouse.Hover(PPI.PPIHome.PPI_Main.PPI_Window.MastersPane);
Mouse.Click(PPI.PPIHome.PPI_Main.PPI_Window.DestinationMasterPane.DestinationMasterHyperlink);
}
The application doesnt run after this exception.I am using IE 8 as my browser to run the application.But when I run the application ,IE mode is changed automatically to compatibility mode.Is this related to the exception?
Is there a way to resolve this issue and get my application to running.Thanks in advance.
Does the hover work? Can you hover over the link instead to make sure that works? What happens when you find the control from the UIMap?
What does PPI.PPIHome.PPI_Main.PPI_Window.DestinationMasterPane.DestinationMasterHyperlink.TryGetClickablePoint() return?
Does the UI need to scroll to see the link? If so you could use PPI.PPIHome.PPI_Main.PPI_Window.DestinationMasterPane.DestinationMasterHyperlink.EnsureClickable() to scroll to the control.
Try to use WaitForControlReady() to make sure the page is fully loaded before coded ui acts on it. Sometimes coded ui can move faster than the application under test.
Make sure you have the latest update for VS2012
