XAML button bound to ReactiveCommand does not get enabled when execution finishes

[Atle]

Hi,

I have a ReactiveCommand bound to a XAML button like this:

XAML:

<Button Content="Update" HorizontalAlignment="Right" Command="{Binding CreateSeries}"/>

ViewModel:

public ReactiveCommand<IList<IChartSeriesViewModel>> CreateSeries { get; protected set; }

In ctor:

CreateSeries = ReactiveCommand.CreateAsyncTask(_ => CreateSeriesImpl());

CreateSeries.Subscribe(chartSeriesViewModels =>

{

    SeriesCollection = new ObservableCollection<IChartSeriesViewModel>(chartSeriesViewModels);

});

The async dummy task:

private async Task<IList<IChartSeriesViewModel>> CreateSeriesImpl()

{

    const int nSimulations = 100;

    IEnumerable<Task<Data>> readDataTasks = Enumerable.Range(0, nSimulations).Select(ReadData);

    Data[] datas = await Task.WhenAll(readDataTasks);

    return datas.Select(CreateChartSeries).ToList();

}

When I press my 'Update' button it id disabled as expected, however, it never gets enabled again even though the task finishes and my plots gets updated. Is there something I am forgetting? Shouldn't the button get enabled automagically when the task finishes?

Another thing, I tried using ReactiveList instead of ObservableCollection, but the plot would never update (SciChart by the way).

Sincerely

Atle

How about like this?

CreateSeries = ReactiveCommand.CreateAsyncTask(_ async => {

SeriesCollection = new ObservableCollection<IChartSeriesViewModel>(await CreateSeriesImpl());

});
