<br> Indika,<br><br> I will need to reproduce the problem in order to investigate and fix it. If you can create an isolated test case and open a jira for it, it will be very helpful.<br><br> Thanks,<br> Edson<br>

Hi all <br><br>I have encountered an issue when Droools fusion is run
in the stream mode with 'multithreadEvaluation' and maxThreads=5.
The issue is as follows.<br><br>org.drools.<div>RuntimeDroolsException: Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction@8c1400<br>

... 25 more<br><br><br>Then NPE is due to the argument 'context' of the accumulate is null. <br><br>When I run the fusion in the same scenario without 'multithreadEvaluation' , it works fine. <br>
<br>Could someone help me to identify the actual issue?<br><br>Thanks Lots <br><br>Indika <br><br>Please Note : I did not inject events concurrently. But , I need to do that too <br>
