Event Preprocessor and the Rete Network
Since this project uses Cache Only mode, after each RTC the data created in the agent is saved to the cache and removed from the Rete network.
Before the next RTC, therefore, you must reload any data needed by any rules that will be triggered in the RTC. This is generally done using the event preprocessor rule function, as it is the presence of event data that triggers most rules.
Learning Points
Loading data from cache into the Rete does not trigger rules
At least not in the way it would if the data was newly arriving in an event. In conjunction with other data, however, the presence of the loaded data can trigger rules, in the usual way.
