[kepler-users] string splitter

[Corinna Gries]

Hi Madhu,

when I run the attached workflow the output is this:

{"6/19/2009", "CEW", "", "6/10/2009", "6", "1", "1000", "52.5", "31", 
"1", "1", "1.017410714", "0.625589286", "1.3125"}

and it is missing the empty string in position 14. I think you may have 
had a space after the last comma, which made it work just fine.
