I am working with several Looping component examples. In Rhino 9 SR1 (9.1.26314.09001), changing the Loop Repeater value with a slider or manually will not trigger the Looping cluster to recompute.

I have to manually “Recompute Solution” in order to see the effects of changing the values of the looping cluster. An example file is attached.

It is possible to implement a self-iterative mechanism that automatically determines when the loop should terminate, using a “loop break.”

While this approach is more complex, it dynamically adjusts whenever the number of loop iterations changes.

An example file is attached.
