Possible Error in Scripting Example in How to Extend RapidMiner tutorial

Hi there,
To be aware, it looks like there is a small bug in the scripting example in  "How to Extend RapidMiner 5".  There is an extra left bracket on the line.  I had to match it on the right to get the script to work.

A very,very  small thing, but this might save other newbies a half hour of debugging as the compilation error (see below) was misleading so I missesd the obvious error.  If I am correct, can you correct the document?

Thanks,
John.
