algorithmic modeling for Rhino
It seems to me that clusters with a containing "Null Item"-Component don't work. When working inside the cluster everything is ok, but after closing it turns yellow. this occurs both in the 08.66/Rh4 and in 09.14/Rh5.
(I have to use the "Null-Item" quite often, since the "ReplaceNulls" doesn't replace empty Lists)
Any ideas how to work around this? or do I have to insert the group over and over?

The problem is not with the "null item" component in the cluster, but the fact that clusters do not properly handle receiving empty inputs. I keep a "create null item" script handy as a workaround for these situations - as long as a cluster receives SOMETHING, even a null value, it will function properly. I feed it in along with whatever regular inputs the cluster is supposed to receive. The script looks like this:
private void RunScript(ref object A)
{
A = null;
}
This is an annoying bug, and has come up before. David....?

I'm on the road now but I'll try and take a look at this before 0.9.0015 goes out. It's probably just a matter of marking all Cluster inputs as OPTIONAL so they don't prevent the cluster from running if they're empty.

I made it so that all cluster inputs are now optional. We'll see whether it works any better this way.
