I am new to Pentaho and Weka.

I am trying to do forecasting using Weka Knowledge Flow. I am using Weka 3.9.1 version.
Weka Timeseries forecasting component works perfectly fine without selection of rebuild/re estimate on incoming data.
Once I select it for autorefresh purpose, it starts giving me same error Caused by: java.lang.Exception: All values of the time stamp field (Date) were missing in the priming data!I even tried with standard sample datasets- airlines.arff and wine.arff
Both the times same error coming.

Dear Mark,

If you can please guide what is the issue.
