You should check out some of the examples at the ilog exilir page.. i've said this before they have some good examples... are you adding a collectionEvent to your collection? You should be adding an eventListener so that when your collection refreshes you can do everything you need to. You can see if the collection has refreshed properly by checking the return value from the refresh method
