eid := ctxElem.Entity.ID
hasUpdatedMetadata := hasUpdatedMetadata(&ctxElem, tb.entities[eid])
tb.entities_lock.Unlock()

// propogate this update to its subscribers
go tb.notifySubscribers(&ctxElem)

// apply the new update to the entity in the entity map
tb.updateContextElement(&ctxElem)

// register the entity if there is any changes on attribute list, domain metadata
if hasUpdatedMetadata == true {
//fmt.Println("===========has updated metadata============")
tb.registerContextElement(&ctxElem)
}
