Haxe error when overriding SetupPlayerInputComponent

[yuhe00]

When overriding SetupPlayerInputComponent in an APawn actor like this:

	override public function SetupPlayerInputComponent(InputComponent:UInputComponent) {
		InputComponent.BindActionHxVoid("Action1", EInputEvent.IE_Pressed, this, onAction1);
		InputComponent.BindActionHxVoid("Action2", EInputEvent.IE_Pressed, this, onAction2);
		InputComponent.BindActionHxVoid("Action3", EInputEvent.IE_Pressed, this, onAction3);
	}

I get this when I run the game.

HaxeLog: Error: HaxeCodeDispatcher.hx:75: AKFTargetedPawn.SetupPlayerInputComponent: The object at index 83615 (UInputComponent) had incompatible serial numbers: 38173 != 0
