Transparent emitter not working

Hi all
I want to configure a transparent emitter, but when I put the opacity to 0 it stops emitting. Also the power of emission is modulated by opacity parameter.
As I've seen from others in the forum, it should not be so, emitter should be independent from opacity, wouldn't it?
The problem with this is that I cannot make the emitter disappear...
any idea?
Thanks

Well, you can't make emitters disappear, because if they disappear, you can't see the light they are emitting. Somehow logical, isn't it?

Thanks for the answer
Maybe I missunderstood the thing, but in this topic I don't know how but they managed it:

I just gave it a try and it does work in beta 2.44. Maybe you can post an example scene that does not work.

Sorry, I couldn't answer earlier.
I was trying to create a glass emitter throug a mix material (It's an easy way to make night scenes of exteriors of buildings without need of design the ilumination).
Is in a premade scene I have were it doesn't work
I suppose it is something wrong with my scene, maybe a normals problem
The fact is that starting a new scene and exporting it from sketchup it has worked (scene attached).
In the scene attached, the cilinder is an emitter and it works. If you click on "light" and go to the standard material object, it happens what I said (the same than in my other scene): opacity modifies emission
Thanks
cheers
