No "Expose on Spawn" option for 'class' variables

I’m trying to pass in an array of actor classes into a blueprinted actor in its construction script so that it can later spawn objects from those classes, but I noticed that “class” type variables don’t have a “Expose on Spawn” option, therefore I cannot pass in the array of classes I need when spawning this actor. Why can’t “class” variables be exposed on spawn?

(Note: I noticed “text” variables also don’t have this option)

Oh, odd, I just discovered that a variable that holds classes is automatically exposed on spawn if marked as “Editable”. Slightly out of the norm and not obvious, but it solves my problem.

After further experimentation, it turns out that the automatically exposed array of class variables doesn’t work; it does not actually initialize the array with the array that is passed in on spawn. Aside from that, it turns out that a single instance (not array) of a ‘class’ variable does not automatically get exposed on spawn. So it looks like this issue is still valid.

To note, this is with version 4.4.0 of the engine.

I noticed this myself, seems weird to have to create 2 variables, one mimicking the other, just to be accessible in the constructor.
