What is the difference between SECA and EECA?
SECA (Service Event Condition Action) and EECA (Entity Event Condition Action) both trigger extra logic automatically, but they hook into different layers of the framework.
| SECA | EECA |
| Fires on a service invocation event (before/after, success/failure) | Fires on a raw entity operation (create, store, remove) |
Defined in a component's *Services.xml alongside the service | Defined in an entity's EECA definition file |
| Typically chains another service as the action | Typically invokes a service in reaction to a low-level data change |

SECA rules react to:
EECA is especially useful when data is changed:
