QUESTION
I'm trying to call functions from external components on a custom selector. I've found a method to achieve this, but it won't recognize any of the variables from the component. This is what I've done:
Selector (declared as an entry component):

Another thing is your getting TypeError because of service not initialised while trying to access it in constructor. Move it to ngOnInit() and do check do whether you added them in providers
You need to do some modifications in your component code like below,

I'm developing a simple navigator with mapbox API for Android.
I'm creating some routes using https://docs.mapbox.com/playground/directions/ playground and i would like to use the generated JSON to generate a DirectionsRoute object.
So i call DirectionsRoute.fromJson() but when i do it, the application crashes with this error:
ANSWER
Answered 2021-Jun-15 at 08:12The response from the mapbox API is not DirectionsRoute. It is DirectionsResponse, a structure that looks like this:

I have run into an unexpected (and inexplicable) difference in UI binding behavior between Blazor WASM and Blazor server. Given the following razor component, the "Send" button is correctly disabled during the request, in both Blazor Server and Blazor WASM:
...ANSWER
Answered 2021-Jun-09 at 22:11I'm suprised it behaves differently, but there is a significant different between Server and WASM that may explain what's going on. I'm not fully familiar with MudBlazor, so I'm not sure how the MudBlazor internals work exactly.
The difference being that the browser has only a single thread for all operations. Server as as many as are available on the server instance, which is almost all cases is more than one.

QUESTION
I am writing an ASP.NET Core application with Entity Framework Core. I'm also using MediatR.
When I trigger a database update, be it save or delete, I get this error:
Cannot access a disposed object. Object name: 'IServiceProvider'
It sometimes happens on the first try, sometimes on subsequent ones. I can't seem to find the pattern.
What I did manage to do is hit the breakpoint in handler which calls await _applicationDbContext.SaveChangesAsync(cancellationToken); although the error actually gets thrown in controller, on await _mediator.Send(someRequestModel);. After the error gets thrown, the app goes in break mode and crashes.
I'll use dummy names, but this is the relevant code, I think:
Controller:
...ANSWER
Answered 2021-Jun-01 at 18:58You are using an async void in your controller. Async void should only be used in specific scenarios, in this case you should be using a Task as the return type.
QUESTION
Im reading the book of GoF. Could you please explain the following Advantage:
It limits subclassing. A mediator localizes behavior that otherwise would be distributed among several objects. Changing this behavior requires subclassing Mediator only; Colleague classes can be reused as is.
Is it meant that we should subclass the Mediator or the ConcreteMediator? Can we have more than one ConcreteMediators that inherit form the same Mediator?
...ANSWER
Answered 2021-May-31 at 06:15The book is written in or before 1994, and mainly with examples in C++. Thus, it uses inheritance heavily, partly because C++ allows multiple inheritance, and partly because the language has no separate concept of an interface (like Java or C#).
Early in the book, it states as a goal:
Favor object composition over class inheritance.
Implicit in the book is the understanding that inheritance may not be the best mechanism for reuse.
Consider the example given for the Mediator pattern: the font dialog. Without a Mediator (FontDialogDirector) the ListBox would need to directly know about the EntryField in order to update it about its state change.
A general-purpose ListBox should be useful in many contexts, with or without a collaborating EntryField. Thus, a reusable ListBox class can't know about any 'colleagues', because that would make it non-reusable.
Thus, without a Mediator, you'd need to subclass ListBox to connect it to an EntryField. In pseudo-C# it might look something like this:
QUESTION
I have made a lightweight mediator kind of library for use internally.
A query can be mapped to a async method without the caller knowing anything about it.
...ANSWER
Answered 2021-May-27 at 11:37As as been commented already, the optimal solution would be to have async all the way... but sometimes that's not possible. Even Microsoft has acknowledged this by having a tool in their own frameworks to run async methods synchronously:
QUESTION
I'm responsible for the testing of a legacy software developed in C and C# that my team is maintaining. The original team used NSubstitute 3.1 to create test doubles for delegates in order to perform unit test of the APIs for the C# sections. Here's one such test double, where irrelevant details have been omitted:
...ANSWER
Answered 2021-May-12 at 23:47specify a "catch all" behaviour for the values that won't match the expectations
I think I've found a way you can do this. If you first stub the "catch all" / failure case for all arguments, you can then stub more specific calls. NSubstitute will try to match the most recent specifications provided, falling back to earlier stubbed values.
Here is a sample.
Note it is using Configure from NSubstitute.Extensions namespace introduced in NSubstitute 4.x. This isn't strictly necessary because NSubstitute will automatically assume you are configuring a call if you are using argument matchers, but it is a good pattern to use when configuring overlapping calls like this.
QUESTION
I created an object called Model that has some methods. I want to import Model into Mediator to use its methods there. But when I try to do this in Mediator.m I keep getting errors:
Initializer element is not a compile-time constant & No known class method for selector 'add'
I'm confused at to what these error are getting at. Researching them has not made things more clear.

QUESTION
What my program supposed to do : My goal is to create a windows service which acts as a mediator between multiple SQL databases. In total there are 3 different tables in 3 different servers In detail, when this service runs it should oversee the data in the "Table1" and copy it to the "Table2" in periodical time(every 1 minute). But tricky part is it cannot paste duplicate records, has to check for "Table2" 's ID field and validate for not pasting the same record with the same ID.I've added a diagram for understanding purposes of what my goal is
What I've done : So far I've developed the code completely but the issue is it only copies data from one table(specifically "NOR_LABOR" according to the diagram I've attached) to "DEV_Test_Nor_Data" in the "MES_DEV" Database(con1 to con2). According to the diagram con1, con3, con4 are tables "NOR_LABOR", "SETTER_LABOR" and "wrap_labor" respectively. con2 is the destination which is "MES_DEV" DB.
Can anybody figure out why does other table's data(con3 to con2 & con4 to con2) won't copy?

QUESTION
I have been trying out Apache Synapse and been trying to use the JavaScript mediator to set the JSON payload. But the ScriptMessageContext class doesn't contain any method for reading a JSON payload or setting a JSON payload. But there has been numerous examples of setting and getting JSON Payload in WSO2 such as mc.getPayloadJSON(); and mc.setPayloadJSON(response). Is there anyway to workaroud this in Apache Synapse?
ANSWER
Answered 2021-Feb-11 at 05:40I found the answer for myself.Synapse process every data by converting it into soap.So first I needed to convert the flow flie to soap. Then processed the data using javascript and convert the script back to json using xslt. The complete xml code is shown below.Here I used synapse as proxy to send a get response from another server. then the data from that api is converted to soap and then processed in javascript and converted back from soap to json and send back to client.
