I must say I haven't tested the plugin with Grails 2.3.x
There was another complaint in regard to the version, but I hadn't had a chance to deal with it yet.

I'm getting the same error in Grails 2.2.4. event.entityAccess is always null.

There are two contructors in AbstractPersistenceEvent. One with EntityAccess and one without. The second one sets entity and entityAccess to null and populates entityObject instead. That one is obviously used. So in AuditEventListener you have to change the lines in the respective events from

void onPostInsert(PostInsertEvent event) {
====> OLD def entity = event.entityAccess.entity
if (elasticSearchContextHolder.isRootClass(entity.class)) {
pushToIndex(entity)
}
}

to

void onPostInsert(PostInsertEvent event) {
====> NEW def entity = event.entityAccess?.entity ?: event.entityObject
if (elasticSearchContextHolder.isRootClass(entity.class)) {
pushToIndex(entity)
}
}

I've pushed a fix.
Thanks everyone, your help is much appreciated!
