[Building Sakai] Events

[Stephen Marquard]

In 2.6+, you can explicitly pass the context when posting the event.

Hi Adrian,

It looks like it's set in BaseEvent which implements Event:

kernel-impl/src/main/java/org/sakaiproject/event/impl/BaseEventTrackingService.java

// Find the context using the reference (let the service that it belongs to parse it) 
			if (resource != null && !"".equals(resource)) {
				Reference ref = entityManager().newReference(resource);
				if (ref != null) {
					m_context = ref.getContext();
				}
			}
			
			// If we still need to find the context, try the tool placement 
			if (m_context == null) {
				Placement placement = toolManager().getCurrentPlacement();
				if (placement != null) {
					m_context = placement.getContext();
				}
			}


So the context comes from either the entity reference or from the tool placement. I'll take a stab and assume you are working on events for the system wide chat? You probably don't have either so its null and SiteStats can't determine where they came from. Might need to extend Event to take a context parameter in its constructor, or run a regular quartz job over it to fix all of the null context events (any from <2.5 will be null also) so they can be collected in SiteStats.

cheers,
Steve
