On visual studio 2017, Win10, in a new relativity client project
datamodule -> right click “remoteDataAdapter” (LinqRemoteDataAdapter) -> Reset Calls To Defaults
This action add new parameters without deleting old ones in:
remoteDataAdapter -> DataRequestCall -> Parameters
remoteDataAdapter -> DataUpdateCall-> Parameters
remoteDataAdapter -> SchemaCall-> Parameters
When deleting manually this parameters from ide, in DataModule.Designer.cs some lines code remains.
Hello
What language do you use in the project where you see this issue?
C#.
I have found this also in client/server application, after changing ClientChannel.targetUrl to another IP.
I was not able to reproduce any issues on the latest VS 2017 and RO SDK build.
This issue happen often.
You can reproduce it:
create a new DA client/custom server application
open DataModule, select channel, change TargetUrl (visual property)
if you open DataModule.Designer.cs you can see:
#region Component Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()

For make the project work again i must delete mannually all code relative of duplicated dynamicRequestParameter.
What exactly doesn’t work for you? I don’t see any duplicated parameters here.
Also reproduce steps are not full because none of our generated projects contain name like ipHttpClientChannel1.
This is the exception in client project.

In attachment a simple NET solution with:
This is a sample to reproduce this error, but it will occour also in other way, randomly in project when i update entities or configuration.
Thanks for the testcase. IT seems like a some kind on WinForms designer bug in VS 2017. We’’ need to investigate this deeper.
Please reattach the OnLoginNeeded event handler to the client channel and this exception will be resolved. It means that one tries to access data w/o loggin in first.
Thanks, logged as bugs://79015
