"java.lang.NullPointerExceptiond:when using Voting inside X-Validation"
New Altair Community Member
Updated by Jocelyn
Helllo,
I a trying to use a voting operator inside X-Validation but it fails. In the log I can find a java.lang.NullPointerException. The same happens when I use stacking as well, but only sometimes and I am not able to reproduce it now.
I am using RM 5.3.01, so the latest update.
Best,
Elena
