[rules-users] ClassCastException: org.drools.reteoo.RuleTerminalNode$TerminalNodeMemory cannot be cast to org.drools.reteoo.EvalConditionNode$EvalMemory
Hi all,
We're receiving some error messages that we don't understand from rules that had
conditionals that worked and now don't (no upgrade or anything like that, they just
stopped working), any clues as to what kinds of things to look for when we get an error
like the following? (if not we can try to pair down to an a test case)
org.drools.runtime.rule.ConsequenceException: java.lang.ClassCastException:
