Anchors or nested shapes? [message #710859]

I'm a newbie at Graphiti, I'm designing some editor that has some similarities with this GMF tutorial example. Basically, my nodes are functions with (distinct, named) inputs, and outputs, each connections links an output to an input. I'm trying to decide between two approaches:

1. each individual input/output is an anchor (fix point) of the function node (as in most graphiti examples)
2. each individual input/output is a nested object/shape of the parent node (as in that gmf tutorial)

I will have many different functions (they are not necessarily known at compile time) - but once a node is created, it's function "signature" (inputs and outputs) is fixed. Perhaps some inputs can become hidden (by user action or by the domain).
I'm (slightly, hesitantly) tending to approach 2, but I didn't see any Graphiti example of that approach, and I wonder if that is feasible or advisable.

Any opinions?

In my opinion the 2nd approach is the better one. You have more possibilities for the graphical representation. For this nested shapes you should use chopbox anchors.
