Referencing Blueprint Interfaces as UPROPERTY

[cygon]

Please read my original post.

A) I have a C++ class (let’s say, a custom PlayerController) that has a UPROPERTY:

Now I thought my C++ player controller could be given a property like this:

/// Dialog to which input is currently being sent (can be null if no dialog is active)
public: UPROPERTY(EditAnywhere, BlueprintReadWrite, Transient, Category="UI")
TScriptInterface<IButtonControllableDialog> ActiveDialog;

I am not trying to add a UPROPERTY to a blueprint interface.
