This isn't a good idea, it's fairly common for widgets to have a "None" option which isn't expected to have an input.
What i changed is mux widgets, i'm wondering is it possible or correct the mux widget has no input path? If i understand correct, we may need set correct input path for mux widget, or why we still need a mux?
Or can you help give an example that no input needed for mux widget?
The above is the most common example - one of the inputs to a mux being a "no input" option which shouldn't be connected to anything. A mux with no inputs at all would be silly, but having one (or sometimes a couple for various reasons) that isn't connected isn't unusual.
