Half refracted object gives totally black alpha channel

[MikkoK]

Hello.

I'm struggling with transparent objects and alpha channels. For the test, I have two box objects, one behind the other. Both of them have refract color about 210, 210, 210. I'm trying to get gray alpha for the front object and a bit darker color where the two objects are intersecting. But all I get is totally black alpha for both of them. Also the plane is not affected behind the refracted objects. I've tried to affect both color+alpha and all channels options.
Below is two pictures, the render and the alpha channel. I don't know if I'm missing something here..?

Any help would be nice. Thank you.

Are you sure you setting the affect alpha all channels in the refRACTION, and not accidently in reFLECTION?

Well then, actually I put them for both by accident, even I wasn't using any reflections and that was the reason why I got totally black alpha. So that is now solved, thanks!
But now when I use a bit of reflection, I lost the transparency depth in alpha channel. As below. Can I somehow combine those two?
