<pre>mathematical expression got only evaluated for toString/getMeasure, but for actual setup of filter/classifier. Didn't pop up as error since most Weka schemes do NOT check the input in the get-method (you only get wonky results). Was discovered by M. Fatih Akay using LibSVM, since LibSVM threw an exception in case of invalid parameters, but the values would have been valid IF the expression would have been evaluated.</pre>
