Scala Worksheet evaluating old code

Question

I'm new to Scala, so I apologize if this question seems trivial. I use Scala tables to evaluate some of the classes that I wrote, and it seems that the worksheet that I use does not evaluate the last compiled code.

For example,

I have a method that does the following:

def randomPermute(xs: List[Any]): List[Any] = {
    randomSelect(xs.length, xs)
}

which after the initial compilation and evaluation of the base list produced:

List('f, 'a, 'c, 'd, 'b, 'e)

However, after I changed this method to

def randomPermute(xs: List[Any]): List[Any] = {
    //randomSelect(xs.length, xs)
    Nil
}

After re-evaluating with the sheet, I still get a random permutation of the list.

Is there an error in the settings of my project?

Am I just misunderstanding Scala?
