In this case, since you are just adding a new element to the ArrayCollection, that ArrayCollection would receive a CollectionEvent.COLLECTION_CHANGE. I think you'd also see some indicate of the update collection message being pushed to the client in the server logs... I don't remember seeing that. Assuming you are still not seeing the message on the client and you can upload your code I'll take a look. I have mysql here of course so that is no problem.

I also used the 'message' and 'propertyChange' events on my mxml DataService tag to check if anything is incoming. It seems that the client does not receive any of these events (I expected a propertyChange event) Shall I try and upload the code?
