No I have a minimal setup with gedit + emebedded terminal for editing files and a differrent terminal open for testing individual functions...and of course i use 'lein new' and load-file to load my namespaces in.

But *how* are you using leiningen2 to test this? With swank & Emacs?

    Well, suspect or not that is what is happening under
    leiningen2...in all fairness this rarely happens - ususally the
    errors originate from my code and sometimes for really
    "complicated" stuff i have big stack traces...this particular
    example is very straight forward, all the functions have been
    individually tested and there is practically no nesting (a
    function calls another and that is it!) - that is why it seems so
    strange and that is why i resorted here...Believe me very rarely
    is spend 2-3 hours on an error and incidently it happens mainly
    when I'm using java interop extensively...

    clojure.lang.Numbers.doubles_array takes a Number or ISeq.

    The fact that you're not getting precise line numbers for the
    error in your own source is suspect. How are you compiling and
    testing your code?

        But it is already a double array, or at least it should be
        because that is what normalize returns...Why start copying
        into a new array?

        anyway, I tried it and i get this instead:

        ClassCastException [D cannot be cast to java.lang.Number
         clojure.lang.Numbers.double_array (Numbers.java:1068)

        I don't even know where that comes from!!! any ideas?

            You probably want to use double-array rather than
            doubles. The former
            creates an array, the latter is a cast.

                ps: function.png shows the function thatis being
                returned by make-data when
                passed the key :temporal-window.

                    the array become an

                    array with 'doubles' doesn't
                    work?


                Can you post the whole stack trace?
