[rules-users] Using DSL and accumulate in Drools BRMS leads to unexpected results

[pentarious]

Thanks,
I just opened a JIRA: http://jira.jboss.com/jira/browse/JBRULES-1219
Should I open a JIRA for the following problem, too?
http://www.nabble.com/org.drools.base.accumulators.CountAccumulateFunction-error-with-Drools-BRMS-4.0.1-tf4414590.html#a12592552

Regards,
