When you use Cache Only mode for an entity type, objects of that type behave normally when they are created during an RTC (see Understanding Conflict Resolution and Run to Completion Cycles for more details). At the end of an RTC, however, they are removed from the Rete network and written to the cache.
You must explicitly load Cache Only objects into the Rete network when they will be needed during an RTC, using an appropriate cache load function in the DataGrid function category, within the Cluster category:The functions that load concepts by ExtID or ID have a parameter to control whether contained concepts are also loaded. The CacheLoadParent() function, which loads a given concept’s parents, has the option to return all parents or the immediate parent. (Parents are concepts related to the given concept by a containment relationship).
Referenced Concepts You must explicitly load all referenced concepts as needed. Only containment relationships can be handled automatically.
Limited Use of getByExtId() Only use this function to retrieve Cache Only objects that have already been loaded into the Rete network by a preprocessor. The getByExtId() function does not load the object into the Rete network.
