How can I manually redraw the children of a GraphNode after updating their properties

I am using the GraphNode and dynamically adding it to a GraphEdit via drag/drop. Each GraphNode represents some data in an underlying object called Persona. The GraphNode contains a TextEdit, a Label, an ItemList and an invisible WindowDialog.

I use the ItemList within the GraphNode to allow the user to choose actions on the GraphNode (edit or remove).

# this function pops up dialogs based on selections from am item list
func _on_ItemList_item_selected(index: int) -> void:
	# Edit the persona information in the node via a popup
	if(index == 0):	
		$PersonaProps.dialogMode = 1
		$PersonaProps.inputId = int($lblId.text)
		$PersonaProps.popup_centered()
	# delete the node after confirmation
	if(index == 1):
		$dlgConfirm.popup_centered()

When the user chooses Edit from the ItemList (0), I popup a modal WindowDialog where they can update the underlying Persona object. When the user saves the information in the modal dialog and it closes, I emit a global signal that invokes a function in the GraphNode to update the TextEdit and the Label.
(Note that I am doing a lot of print statements for troubleshooting purposes, and the results are all positive, in other words the node contents are updating)

# this function is called by a global signal when the node needs refreshing		
func _persona_refresh(personaId) -> void:
	print("Refreshing existing Persona :" + String(personaId))
	_load_persona(personaId)
	

# this function reloads the information in the graphnode from the persona object
func _load_persona(personaID:int):
	print(String(personaID))
	persona = Persona.new()
	persona.Open(personaID)
	print(persona.persname)
	print(persona.persdesc)
	$txtDescription.text = persona.persdesc
	self.title = persona.persname
	$lblId.text = String(persona.id)

My problem is that the new information does not display in the GraphNode after calling _persona_refresh. If I remove the node and re-add it to the GraphEdit, the new information shows up.

I have tried various ways to manually update the GraphNode at the end of the _load_persona function call, including:

  • update()
  • get_parent().update()
  • hide() then show()
  • resizing the control
    but to no avail. Has anyone else had this issue? What else can I try? Is there something wrong with my architecture?

Thank you for any help you can give.
