<br> Jeff,<br><br> What mvel version are you using? (take a look at the jar name)<br> If it is not 1.3.9, try it out to check if the problem still happens.<br><br> []s<br> Edson<br><br><div class="gmail_quote">2008/11/19 hongyu lu <span dir="ltr"><<a href="mailto:hl_107@yahoo.com">hl_107@yahoo.com</a>></span><br>

<br>
I am seeking some help here for a very weird issue we ran into with drools <a href="http://4.0.7." target="_blank">4.0.7.</a> The error is intermittent but once happens it will be consistent for the rest rule evaluation.<br>
<br>
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<br>
t. Some parsing related problem? Any advice on how to debug this kind issues?<br>
<br>
thanks a lot for your help!<br>
Jeff<br>
