[rules-users] fact updates with query-only usage of Drools

Dear All, In a multithreaded application I plan to use Drools the following way: -use only queries but not rules -keep an outside reference to all facts inserted into the working memory, and keep modifying the facts after they were inserted -use locks synchronizing outside fact changes and Drools query executions (happening parallelly on other threads), to make sure that when the queries are executed, the facts are always in a consistent state Given that the application only uses queries (and no rules), I wonder if there is a need to notify the engine of the fact changes (e.g. workingMemory.update(...) etc.). Could someone confirm that? Thank you, Andras
