macOS: TableView group name does not update

I slightly modified view of template application

    let view (model: Model) dispatch =
        View.ContentPage(
          content = View.StackLayout(
            padding = 20.0, verticalOptions = LayoutOptions.Center,
            children = [
                View.TableView(
                    intent = TableIntent.Form,
                    items = [
                        (sprintf "%d" model.Count, [
                            View.TextCell(
                                text = sprintf "%d" model.Count
                            )
                        ])
                    ]
                  )
                View.Button(text = "Increment", command = (fun () -> dispatch Increment), horizontalOptions = LayoutOptions.Center)
                View.Button(text = "Decrement", command = (fun () -> dispatch Decrement), horizontalOptions = LayoutOptions.Center)
            ]))

when I click buttons, content of View.TextCell updates correctly, but group name does not

If it is by design, then it is confusing.

Sooo… It’s a Xamarin.Forms bug finally. 😃 The code above is not what Fabulous does.

Fabulous reuses TableView.Root if not null, which is the case by default in Xamarin.Forms. And for some reasons, this default value ignores property changed events, where a new TableRoot will not.

So I will change the way Fabulous works and raise an issue on the Xamarin.Forms repo.

Thanks for reporting. I think I know why, had a similar issue with ListViewGrouped a few months ago. I’ll try to fix that today.
