    If it is not firing, it is a bug. Although we fixed several related bugs
for 4.0.1 that shall be out soon.
    If you can provide a test case and open a Jira, I can do some further
debugging. Essentially, the difference between the rules is that expression
in the first rule is being converted into an MVEL expression, because of the
nested accessors, while the second is a pure drools expression.
