Transmit Step fail on Windows client

[Former Member]

Hi,

I have added a Trasmit on an action to retrieve through oData service some information of an equipment from ECC. Nowadays, it works fine on ipad and android client, but when I try to use this action from Windows Client the application crashes and I get the following error on windows log:

and this screens of my action:

Thank you for your help.

Fabbian,

So from what you stated above:

~~~~~~~Start Here~~~~~~~~~

Applicazione: AgentryClient.exe

Versione framework: v4.0.30319   <-- YOUR VERSION is Version 4.0.30319 (Is this correct - I have not seen version 4 in a long time?)

Descrizione: il processo è stato terminato a causa di un'eccezione non gestita.

Informazioni sull'eccezione: System.NullReferenceException

   in AgentryClientDotNET.WindowWizardPage.Cancel_Click(System.Object, System.Windows.RoutedEventArgs)

   in System.Windows.RoutedEventHandlerInfo.InvokeHandler(System.Object, System.Windows.RoutedEventArgs)

~~~~~~~End Here~~~~~~~~~~

Let us go line by line on your error.

1. You have an Agentry Windows Client of Version 4.0.X?
2. Then on the next line you get:  System.NullReferenceException when the AgentryClientDotNET.WindowWizardPage.Cancel_Click was done?

- Why was it canceled?

- This also indicated that something was null on cancel, is this good enough to crash the client?

Is this custom app supposed to cancel the transmit? There may be something missing or not being populated on the fetch properties that you are trying to get from the backend through oDATA.

But from the point of error, the NULLReferenceException is on the Cancel_Click.  Hopefully that is root cause.
