Reusing common Interactions?

[ibrahim324]

I have a ViewModel with an Interaction<Unit, string>, which is responsible of opening a FolderDialog. I "invoke" this Interaction via a Command bound to my view.

private async Task<string> getDirectory()
{
    var dir = await GetDirectoryInteraction.Handle(Unit.Default);
    return string.IsNullOrWhiteSpace(dir) 
        ? string.Empty 
        : dir;
}

I have two commands that i want to use this interaction with:
GetDirectoryCommand = ReactiveCommand.CreateFromTask(getDirectory);
and

MoveDocumentsCommand = ReactiveCommand.CreateFromTask(async () =>
{
    var dir = await getDirectory();
    if (Directory.Exists(dir))
    {
        foreach (var item in this.documents.Items)
        {
....

But i realized that the getDirectory-Interaction returns the same string when i call it in the second command!

Interactions end up "walking" up the stack of registered interactions - if you want to reuse a common one, you can declare it in a common parent View of both elements
