Cracked it. Found an easier and more efficient way to make it happen.
Here's the deal:
I want to bring an existing Align to Spline tag into the Xpresso Editor, add Object and Position ports to the associated node, and then wire these into other nodes that are already present in the window, all via Python, using the Python Generator.
This might be a bridge too far, but I'm hoping it is possible.
Any help or advice on how I might achieve this, will be very gratefully received.
