[Rowanda Ahmed]

Hello Everyone here, I hope that you are are doing great

I tried the IntelliJ as you told me and that what comes with me 🙁🙁 I tried the data
set KDDCup99, I attached it. and choose the clustering tab the ClusTree
algorithm. and by the way, whatever I chose from the clustering
algorithm with any dataset.arff .. it came with these errors

Hello Mr. Peter
but the MOA not only for nominal class
my dataset has only numeric data. is that wrong or difficult for MOA to visulize? and I was working properly with this dataset before four months and it was no problem. I don't know what happened to the moa now to work with this datasets!! You told me that you are submitting a fix to improve the error message. I don't know what's up regarding this issue. thanks so much.

I just downloaded the 2018.6.0 release of MOA and tried to cluster
your dataset. I get the same error message that you initially got
(NullPointerException).

Based on this, I'm not so sure whether you tried to visualize the
clusters using this particular dataset. Maybe you used another
dataset, one with an actual nominal class attribute?

The clustering tab was a contribution and (to be honest) is a bit of a
mess. All we changed was making the error message more informative:
"NullPointerException" -> "IllegalStateException: Class attribute X is
not nominal!"

Please note, I'm not a MOA user.
