Hi, I'm developping an application where logging has some importance. Just so that we're on the same page, let's consider the basics of a log as "who did what and when". "what" and "when" are correctly answered by the log classes but not "who". At least in my case, actorId always returns null. A look at the ProcessLog class tells me that the actorId value is only different from null if it has been set in the parent. However VariableLogs for example don't have a parent and the actorId is not set by jbpm so actorId is always null. Is this a bug or am I missing something? Thanks!
