[Blueprint Only] Setting a FObjectProperty with FieldNotify from Blueprint doesnt broadcast changes as others do.

[jmgomez]

Setting a FObjectProperty with FieldNotify from Blueprint doesnt broadcast changes as others do.

The following code works as expected:

uClass UPlaceableViewModel of UMVVMViewModelBase:
  (BlueprintType)
  uprops(BlueprintReadWrite, EditAnywhere, FieldNotify):
    selectedName: FText
    total: int32
    bIsVisible: bool
    selectedIcon: UTexture2DPtr

  proc update*(selected: USolDataAssetPtr, items: TArray[USolDataAssetPtr], idx: int32) =
    if selected.isNotNil:
      self.selectedName = selected.getName().toText()
      self.selectedIcon = selected.icon
    self.total = items.num
    self.bIsVisible = items.num > 0

However, when setting the prop selectedIcon from blueprints it doesnt notify the change (it does from others).

See the code that handles it (it gets injected in the class constructor)

proc genFieldNotifySetterAssignment(field: UEField): NimNode = 
  let setterName = ident field.name & "Setter"
  genAst(propName = newLit field.name, setterName, propType = ident field.uePropType):
    let prop = self.getClass.getFPropertyByName(propName)
    when not propType is UObjectPtr: #UObjectPtr setters has issues
      prop.setSetter(setterName)
