Created attachment 989915 [details] reproducer Description of problem: Although user update some facts and re-calculation in the accumulate condition is proceeded, rule won't be fired. Using "collect" instead of "accumulate" does not work either. When we comment out "no-loop true" and "update($target)", the rule is fired correctly, but that modification won't be propagated because it was not notified to the engine. If we use "simple" conditions (without accumulate nor collect), it works fine. Version-Release number of selected component (if applicable): - BRMS 6.0.3 - BRMS 6.1.0.ER4 Steps to Reproduce: 1. Download attached reproducer and run JUnit Test written in com.sample.DroolsTest Actual results: Fail the Junit test. (Rule is not fired when user update some facts and re-calculation in the accumulate condition is proceed) Expected results: Pass the JUnit test.(Rule is fired when user update some facts and re-calculation in the accumulate condition is proceed)
This issue has been already reported (in a slightly different way) here https://issues.jboss.org/browse/DROOLS-694 and fixed with this commit https://github.com/droolsjbpm/drools/commit/1484c4fb91b586ae9465ec324304129af0d243ce I checked that the provided reproducer now works on both master and 6.2.x branches.
Setting the target milestone and target release to be included in ER5 testing.
Verified in BRMS 6.1.0 ER5.
