Simple Data Types problem

Hi

has anyone managed to use thir own custom class as an output parameter to a GH component?

I have a node class (see attached) that inherit from GH_Goo/span>Point3d>

Next I have a custom component named CustomClass that takes a point and outputs a node

Last i have a custom component named NodeTest that takes a node and output a point and the property  named connections.

However my problem is that I cannot use the output of the CustomClass directly as input to a ordinary pointComponent

The error i get is this:

1. Data conversion failed from Node to Point

Any suggestions to fix this???
