worse case is we switch to java dialect, although we do need to use jbrms for rule
maintenance. is there a way to force jbrms to use java dialect globally(i tried dialect
"java" in the package header, but didn't seem to work)? we could force java
dialect on each rule but we really want to avoid that. and what would be the down side of
not using mvel dialect in jbrms?
thanks
Jeff

Jeff,
What mvel version are you using? (take a look at the jar name)
If it is not 1.3.9, try it out to check if the problem still happens.

Hi,
I am seeking some help here for a very weird issue we ran into with drools 4.0.7. The
error is intermittent but once happens it will be consistent for the rest rule
evaluation.
We have a fact object called com.like.rules.facts.AllocationFact. But somehow the class
name was messed up when passed to mvel for accessor
optimization:com.like.rules.facts.AllocationFact.facts.AllocationFact.facts.AllocationFac
t. Some parsing related problem? Any advice on how to debug this kind issues?
thanks a lot for your help!
Jeff
