I think we should start discussing how this would best be implemented.  The big questions is, should we do it in BusinessRulesProcessor, or create a new action?  Let me explain....

We could add a configuration option to BusinessRulesProcessor, saying this action instance is only for adding facts into the specified entry-point.  This could prove very confusing, however, considering the ability to specify entry-point names within the object-path(s) configuration section is already there.  What happens if those two names don't align?  ConfigurationException thrown, probably, but why give users the ability to mess up like that?

We could create a new action, perhaps called "EntryPointInserter" (or whatever).  Obviously it would need a config option which somehow identifies the stateful session created by BusinessRulesProcessor.  For clarity of purpose, it's ONLY job would be to insert facts into ONE entry-point.  There would still have to be thread-synchronization done, however.  The most  annoying one would be because you can already insert into entry-points  from BusinessRulesProcessor, what happens if that gets done at the same  time this separate action tries to?  So, we'd have to be cautious of this.

Thoughts?
