Hey Guys,
I am new to RapidMiner and I have to apply Agglomerative Clustering on my dataset. I have the following tree structure of operators

CSVExampleSource->AgglomerativeClustering->performance

when I check the validity of the operator chain, RapidMiner says that it contains no error but when I run it, it gives me an error message like this. I am sending the whole log file. The error message box reads that there is no error in the processes but consult the log file and here is the log file.

  Root[1] (Process)
  +- CSVExampleSource[1] (CSVExampleSource)
  +- AgglomerativeClustering[1] (AgglomerativeClustering)
  +- Performance[0] (Performance)
G Apr 23, 2010 1:54:07 PM: [Fatal] NullPointerException occured in 1st application of AgglomerativeClustering (AgglomerativeClustering)
G Apr 23, 2010 1:54:07 PM: [Fatal] Process failed: operator cannot be executed. Check the log messages...
         Root[1] (Process)
         +- CSVExampleSource[1] (CSVExampleSource)
here ==> +- AgglomerativeClustering[1] (AgglomerativeClustering)
         +- Performance[0] (Performance)

    Hi,
    I would strongly recommend an update to the newest 5.0 version of RapidMiner. Unfortunately we can't support earlier community versions in detail anymore.

    Greetings,
