Errors: "No such column: null" and "No double column in data"

Hi, 

does anybody know what the errors "No such column: null" and "No double column in data" mean? 

I get this error when I try to use the SMOTE node (Oversampling). However when I apply the Equal Size Sampling node (Undersampling) it works totally fine...

Thank you :)

I guess those error messages have room for improvement (will do).

"No such column: null" indicates that you have not selected a class column or the class column no longer exist in your input data.

"No double column in data" tells you that your input data has no numeric columns -- those are needed to draw new samples.
