Exception in "public void Connect"

[Nicola]

Hello Tobii,
provided that I am a novice with C# (I come from Java),
I’ve got the same problem for each C# project I try to start:

An unhandled exception of type 'System.NullReferenceException' occurred in EyeXFramework.dll

at the line

((IComponent)behaviorMap).Disposed += OnBehaviorMapDisposed;

in the function

public void Connect(BehaviorMap behaviorMap)

occurring when called by
Program.EyeXHost.Connect(behaviorMap1);

Do I have to initialize the variable behaviorMap1?
If yes, why it’s not initialized on the EyeXDotNet samples?
How do I have to initialize it?

Thanks for your attention,
Neeque

Hello Nicola,

Are you calling InitializeComponent(); before or after you’re connecting the BehaviorMap to the host instance? Make sure you call it before.

It should look something like this:

public MyForm()
{
    // Initialize form components.
    InitializeComponent();

    // Connect the behavior map to the host.
    Program.EyeXHost.Connect(behaviorMap1);
}

Best regards
Patrik
