Hello Folks,

I updated my rapidminer to 5.3.008 and the following does not work anymore

I am using cross validation operator to split the data into testing and training..I use a decision tree for training  and in testing section I use the Applymodel generated by the decision tree and check the performance.

Reproduce steps:
1.Use X Validation Operator to a dataset
2.Use decision tree in training section
3.Use Apply Model and Performance in the testing set.
4.Run the program

I am getting the following error , setup does not have any obvious error but you should check log for detailed message and in the logs I see the following:


May 30, 2013 10:14:00 AM SEVERE: Here:           Process[1] (Process)

    Hi,

    can you start RapidMiner from the console via the RapidMinerGUI script in the /RapidMiner/scripts folder and paste the exception here (the next RapidMiner version will have an error log which will make this rather tedious step much easier, but until then we have to do it the old fashioned way..)? I cannot reproduce it from your description so it has to be dependant on the data.

    Regards,
    Marco
