Order of the events at the client: onItemUpdate, onEndOfSnapshot

[giuseppe.corti]

Hi Slavko,

I do not think that you have found a bug in Lightstreamer, but maybe I understand the cause of the strange behavior that you observe.

When an Item is subscribed for the first time the adapter should send one or more update with isSnapshot flag set to true and then, optionally, the endOfSnapshot.
But if you send the first update for an Item with isSnapshot flag set to false then you will get the wrong sequence of events because the server infers that for that Item no Snapshot exists. Please refer to the documentation of endOfSnapshot method, I assume you are using Java Adapter API but the concept is the same also in C#.

So if, in your previous posts, you were referring to the first update sent for an Item then it is absolutely correct to have the isSnapshot flag set to true.

Sorry for the misunderstanding.
