New Post: Raised event of InteractionRequest becomes null

Hello Brian,

We have a similar issue but the resolution [RegionMemberLifetime(KeepAlive = false)] is not helping here.

We have a view that opens a UserControl (UC1) as a popup using InteractionRequest<INotification>.

        UC1ViewRequest.Raise(new UC1ViewModel
        {
            Title = "User Control 1"

        });

UC1 has a button that opens another UserControl (UC2) as a popup using InteractionRequest<INotification>.

        UC2ViewRequest.Raise(new UC2ViewModel
        {
            Title = "User Control 2"

        });

Opening UC2 again and again from UC1 works fine as long as UC1 is not closed.

But after closing UC1, UC2 cannot be shown/opened from UC1 but UC1 can be opened again from the main view.

The Raised event on the UC2ViewRequest is null.

Please advise. I can send you a sample to reproduce.
