If it is not firing, it is a bug. Although we fixed several
related bugs for 4.0.1 that shall be out soon. <br>
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. <br>
