I just checked out the sources from the Zaniah branch but i've some problems running it from Eclipse.
When i run the 01_ExampleSource.xml sample i get an error message when the process finishes.
"Cannot instantiate plotter 'Scatter'.
I run RapidMiner with the rapidminer.home variable set to the project directory, as described here http://rapid-i.com/content/view/25/48/lang,en/
I've also tried running RapidMiner from Eclipse with the rapidminer.jar file, which gives the same problem.
Edit: nevermind i had an old version of jfreechart in my JRE dir.
