    @DylanGuedes What about `CodeGenerator.getValue(s"arrVals[$j]", jThChildDataType, i)`?

    I recommend you to use some debbuger to check and understand what gets generated out of
your code or if you don't use any IDE, try to run the following in spark-shell:
    ```
    import org.apache.spark.sql.execution.debug._
    val df = ... create your testing df ...
    df.debugCodegen
    ```
