[JBoss JIRA] (DROOLS-4898) Accumulates: min does not work after retracting fact.
by Mario Fusco (Jira)
[ https://issues.redhat.com/browse/DROOLS-4898?page=com.atlassian.jira.plug... ]
Mario Fusco resolved DROOLS-4898.
---------------------------------
Resolution: Done
Fixed by https://github.com/kiegroup/drools/commit/cf80a213c7a678fe2d39058135e28c1...
The same fix for DROOLS-4896 also solved this problem. Consider however that when you modify an object in the working memory you should always notify the engine calling an update.

> There seems to be 2 kind of issues (root cause might be same though).
> - 2nd accumulate return same min value with 1st one.

> If update is called for the fact like above commented out line, this does not happen.
