As a workaround one can do (in a on-exit action):
drools.getIdentityMap().put(someFact, drools.getWorkingMemory().getFactHandle(someFact));
and then it is safe to call
update(someFact);

Description

Hi,
org.drools.base.DefaultKnowledgeHelper uses newly added identityMap to keep track of fact handles. It looks like this identityMap is updated before a rule's consequence is called. However it is not updated before a Drools Flow on-exit action. This means that calling update(someFact) in a on-exit ruleflow action causes exception ("org.drools.FactException: Update error: handle not found for object: XXXXX. Is it in the working memory?").

this was tested on drools-core-5.0.0.20090417.044049-485.jar

Thanking you in advance.
Best Regards,
Michal
