Operating system: window 10  
Slicer version: 5.2.1

In the case of ‘vtkCurve’ and ‘vtkClosedCurve’ nodes, changing their ‘ **name** ’ is reflected on the screen in real time. However, in the case of 'vtkMRMLMarkupsFiducialNode, even if the ‘ **name** ’ is changed, it is not reflected in real time, and it is reflected in real time only when the **name of ’ Control point’** in a is changed.

When changing the name of ‘vtkMRMLMarkupsFiducialNode’ that exists in the ‘Node’ area of the UI, how is it reflected in the corresponding VIEW in real time?

```auto
SetNodes = slicer.util.getNodesByClass('vtkMRMLMarkupsFiducialNode')
    length = len(SetNodes)
    for idx in range(length):
        SetNodes[idx].SetNthControlPointLabel(0, SetNodes[idx].GetName() )

```

Aha, it works just by coding like this

At far as I remember this issue was fixed in the current Slicer version (Slicer-5.2.2). Always use at least the latest Slicer Stable Release. If you find any problems in the latest version then you can report it here.
