@chrisfilo this is a very useful solution, i was always wondering what was the best way to deal with list of files which could also be a singleton. Would you recommend to use the InputMultiPath class in all these cases then? When i checked the doc for this class it was written "This should only be used as a final resort. We should stick to established Traits to the extent possible". So what would you advise to do? Try to avoid it or go with it in all cases inputs can be either a single file or a list of files?

Interesting. I would use it whenever possible. It just makes life easier!
BTW did you test the solution?
