Reflecting a glowing material

My object is using a miaX material that is being fed by mia_light_surface node to make it glow. It glows nicely but doesn't reflect properly.

If you check out the examples, the color being reflected is from the diffuse color of miaX shader and lacking any intensification created from light surface node. It's reflecting what would be a normal object without any glow.

If I change the color of the node to white, the reflection becomes a regular grey color. The glow effect also has no affect on the cast shadow being created from itself.

I've tried increasing the Secondary Diffuse Bounces in the render globals and even tried piping the light_surface into the diffuse channel but nothing is correcting the reflection. Strange enough, messing with the bounce kills the emmisive properties and darkens the reflection of the object. I have no idea what's wrong with this. I'm using Mental Ray with Maya 2013 in case it helps.

Thanks much,

show your node graph and Attribute editor options for material you used to be more clear

Actually, it's not necessary Mizar since I figured it out.

Not that anyone mentioned it but my question was actually off the mark. I wasn't looking for a 'glow' in the traditional manner. All I wanted was the ramp effect on the sphere to appear in the metal in the same manner.

I was able to get the desired effect by turning the 'Reflection Contribution' in the light surface node to 1. It now reflects properly and a typical glow will be added in the comp phase.

Thanks much!
