ActivateItemAsync don´t work over Dependency Injection

Description

I am trying to create a button which could change ContentControl View via ActivateItemAsync. After a lot of testing it looks like the view can´t be changed. After debugging I found out that the ActivateItemAsync value will be changed but the view just doesn´t change. I don´t even get a error or warning message. Is there a known Bug?

I´ve created a more detailed post here. A hint would be very nice.

I would try using an action message instead of injecting the ShellVM into the view. Like so: <Button Content="Click Me" cal:Message.Attach="[Event Click] = [Action SayHello(Name.Text)]" />

The reason it works when ShellVW is a singleton, is that you don’t get two instances of ShellVW.

Caliburn Micro sets the binding context for the UserControl so there should be no need to inject the ShellVW into the UserControl.

As for the warning I think that is a hard Caliburn Micro cannot guess about the intent of the user code.

Yea on normal redirection I would use the action but I need to translate also a full data object. I used the “A little Extended Implementation” from this post here. It´s the simplest way to use it and it´s also better readable. Maybe we find a better solution in the feature here.
