[rules-users] Please help - losing hair
I'm using Drools 4 (M2), which is supposed to support nested accessors*
This works: when Claim( submissionInfo == null), but not this: when
Claim( submissionInfo.date == null)
Rule file, SubmissionInfo.java and exception are below.
What am I missing?

http://article.gmane.org/gmane.comp.java.drools.user/8079/match=nested+pr...,
which states "Support to nested accessors, property navigation and
simplified collection, arrays and maps syntax"
