Something that should be noted is that in naming inputs/outputs for clusters that there are keywords that cannot be used. For instance naming an output component or parameter "Curve" will cause failure during cluster creation.
If this cannot be easily worked around, can we get a list of reserved keywords?
It must be something else then. That was the first thing I thought of, but I didn't really try to investigate it. Here is a screen shot of the errors I am getting. It looks like a type casting problem?
If you like I can email you my definition to take a look at, it's kinda large and without the data flowing through it the errors are not generated when clusterized.
The component that causes the error appears to be a curve parameter fed by S of an IntCurve component.
