Working with multiple instances doesn't work

[WitmondPaul]

Hi Bruno,

When we connect 2 or more companies using B1Slayer the eventhandling is only working on the last connected company

Example :

B1Connection = new SLConnection(serviceLayerRoot, "LEEG", "manager", "demo"); B1Connection.AfterCall(async call => { TextOk("AC :"+ $"Response: {call.HttpResponseMessage?.StatusCode}"); ResponseBody = await call.HttpResponseMessage?.Content?.ReadAsStringAsync();

        });
        B1Connection.OnError(async err =>
        {
            ErrorBody = await err.HttpResponseMessage?.Content?.ReadAsStringAsync();
        });

        B1Connection2 = new SLConnection(serviceLayerRoot, "SBODEMONL", "manager", "demo");
        B1Connection2.AfterCall(async call2 =>
        {
            ResponseBody2 = await call2.HttpResponseMessage?.Content?.ReadAsStringAsync();
            TextOk("AC2 :" + $"Response: {call2.HttpResponseMessage?.StatusCode}");
        });
        B1Connection2.OnError(async err2 =>
        {
            ErrorBody2 = await err2.HttpResponseMessage?.Content?.ReadAsStringAsync();
        });

In this example the Aftercall event of the first connection doesn't work. If we remove the 2nd the eventhandling on the first company is working fine.

Can this be solved ?

Regards,

Paul

Hi, @WitmondPaul. This can be a bit confusing, but I'll try my best to explain.

The methods BeforeCall, AfterCall and OnError work by setting a global callback that is invoked for every request to a given base Service Layer URL.

So, for instance, if your Service Layer URL is https://yourserver:50000/b1s/v1, all requests made to https://yourserver:50000 should invoke the callback you specified.

In other words, if for both of your SLConnection instances the Service Layer URL is the same, you only need to implement a single callback (in either instance) and it should be called for requests for both instances. If the URL is different, then it makes sense to set it sepparetly like you're doing, otherwise the last callback will overwrite the previous ones like you're seeing, since the URL is the same.
