Edson - please disregard my question on this - we've found out the root cause. The data types of the borrowerNumber and the creditBorrowerNumber attributes, which are deep inside a complex object hierarchy, are different - one is string and one is short. We'll deal with that issue now that we understand it. Thanks for your time. Tom Murphy Business Process Consultant Wells Fargo HCFG - CORE Deal Decisioning Platform 800 S.

If you also observe the incorrect behavior in 5.0.1, I'll try the trunk. If you're not able to, then it must be something I'm doing.

I just tried with trunk and it works fine. I added your test case to the code base, anyway. Disclaimer: I did fixed a couple things in forall last week, not related to your scenario, but who knows? http://fisheye.jboss.org/changelog/JBossRules/?cs=29700 If you can try it with trunk or tell me what version you are using I will check it out.
