    Default Weka Forecasting plugin in PDI

    I have build forecasting model using weka explorer(forecast) gui. I have save my forecast as model in my local system. In PDI add CSV file (step1) and Weka Forecasting step (step2) and then click forecast step and load my model. After that click the Fields Mapping Tab, but unfortunately it is showing empty tab only, even model tab also empty only.

    I have just saved the transformation and try to preview, It showing error "Problem de-serializing model file!"

    Please help me to solve this problem.

    Note: I am using Pentaho EE 5.4 and Weka 3.7.13

    Yes. Its working after replace the pdm-3.7-ce-3.7.11.*.jar file in <PDIinstall directory>/plugins/steps/weka-forecasting/lib with the weka.jar come up with weka 3.7.13.
    Thanks for your solution...

    Cheers
