> The identifier passed to the {{KieCommands.newInsert}} method's {{outIdentifier}} parameter and to the {{ExecutionResults.getValue}} method's {{identifier}} parameter doesn't actually refer to the fact object _via the fact handle_ as described in the documentation of {{InsertObjectCommand}}).
> The documentation says:
> {quote}
> 11.2.2. InsertObjectCommand
> ...
> outIdentifier	Id to identify the FactHandle created in the object insertion and added to the execution results
> {quote}
> Although the Drools code in method {{InsertObjectCommand.execute}} does map the given identifier both to the original object and to the fact handle, the code in method {{ExecutionResultImpl.getValue}} retrieves the _original_ object instead of retrieving the object _currently associated with the fact handle_.
> This means that if the original fact object instance is replaced with a different instance (e.g., with {{update(kcontext.getKieRuntime().getFactHandle($oldObj), newObj);}} in the rules), then {{ExecutionResults.getValue}} will return the _original_ fact object, not the _current_ value of the fact object (the object instance currently associated with the fact handle created in the {{newInsert}} call). 
> That in turn means that immutable fact object instances cannot be used with {{ExecutionResults.getValue}}.
> (It's not 100% clear that it's the code that is wrong (relative to the documentation) rather than it being documentation that's wrong (relative to the code).  However, the behavior described by the documentation seems more useful than the behavior exhibited by the code.)
