onCommandSecondLevelItemLostUpdates method

Event handler that is called by Lightstreamer to notify that, due to internal resource limitations, Lightstreamer Server dropped one or more updates for an item that was subscribed to as a second-level subscription.

Such notifications are sent only if the Subscription was configured in unfiltered mode (second-level items are always in "MERGE" mode and inherit the frequency configuration from the first-level Subscription).
By implementing this method it is possible to perform recovery actions.

• lostUpdates The number of consecutive updates dropped for the item.

• key The value of the key that identifies the second-level item.
