[rules-users] threw error java.lang.ClassCastException: org.drools.reteoo.FromNode$FromMemory cannot be cast to org.drools.reteoo.BetaMemory

[mohdejaz74]

I use KB methods directly

For adding/updating a rule, I create a temporary instance of
KnowledgeBuilder and add the rule to check if there are any errors.

If there are no errors, I first remove (if rule needs to be updated) the
previous rule by calling this ...

kb.removeRule(ro.pkg, ro.name);

Then I add the new rule ...

kb.addKnowledgePackages(kbuilder.getKnowledgePackages());
