Hello list, I'm getting this error:
*java.lang.RuntimeException: Could not forward element to next operator* *...* *Caused by: java.lang.NullPointerException: in com.entities.Sector in map in double null of double of map in field properties of com.entities.Sector* *...* *Caused by: java.lang.NullPointerException* The field mentioned is a HashMap<String, Double>, and some keys are mapped to null values. Why isn't it possible to forward/serialize those elements with null values? What do you do when your elements may contain nulls? Regards, Matt
