title: Exception: Filter didn't make the test instance immediately available
body: <p>I am using the classifier FilteredClassifier in WEKA. The Filter of my classifier is a MultiFilter, doing first InfoGain, and then Standarization.  After training the classifier, when trying to classify the test instances on the fly, I get the error: java.lang.Exception: Filter didn't mkae the test instance immediately available!</p>
  
  <p>Anyone knows how to fix this?</p>
