Type conflict error in MR

[puppetsoul]

I have do a shader for MayaSoftware, and I want use it now with mentalRay (for add displacement).
But when I render I have this error message :

API 0.0 warn 302018: type conflict: "colorGain" is type color, "maya_setrange" returns type vector

And this for 9 connections (including tripleSwitch)

1- how can I know where exactly is the problem (I have some other setRange, and I dont know what node have a problem...)

2- In the doc they say that you can't connect R, G, B value of a 3 collection, but the setRange is entierly connected to the color!

Have you some issue to render this shader with mental ray?

thanks
