Still getting this issue with Zeppelin 0.6.2 while trying to use companion
object
```
class Event(val nuid: String) extends Product {
override def productElement(n: Int): Any = {
n match {
case 0 => nuid
}
}
override def productArity: Int = 1
override def canEqual(that: Any): Boolean = that.isInstanceOf[Event]
}
object Event {
def apply(row: Row): Event = {
if (row.isNullAt(16)) {
new Event("")
} else {
new Event(row.getString(16))
}
}
}
```
Any pointers ?
