[SOLVED] Apply Model ArrayIndexOutOfBoundsException error

Hi all,

I am getting some troubles trying to apply a trained model.

The training process goes smoothly, and after that I store the trained model to the repository (using Store operator).

Then, using exactly the same dataset, when I try to Apply the same model RM throws an Exception :

Jun 28, 2013 5:55:18 PM SEVERE: java.lang.ArrayIndexOutOfBoundsException: DataRow: table index 30 of Attribute att_name is out of bounds.

I've double-checked the dataset and it seems totally correct (no missing values)

Can you help me on this?

Re: Apply Model ArrayIndexOutOfBoundsException error

Hi victor,
which model are you using? If it is a Neural Net, then this is a known bug that has already been fixed in the development version and will be included in the next RapidMiner release.
Otherwise please post both your training and your application process.

Best regards,

Thank you Marius,

As you've said, the model I was using was Neural Net.

Happy to hear that it's corrected
