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...

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.
