Hi Giuseppe,

Thank you for your reply.

I have actually already included the function

var isSnapshotAvailable =function( itemName ){ return true };

in the data provider constructor. I am not sure I understand why if you send isSnapshot flat = true they will be turned into regular updates? I thought that they the whole idea is that you needs to set this flag to true create the initial snapshot in the Lightstreamer server?

Just to make it clear, the snapshot is working fine for the 2nd and 3rd clients that subscribe, I only have the problem mentioned above when the first client subscribes. I believe that this is a problem due to the limitation that a snapshot is only available in the LS server if at least one client is subscribed.

Look forward to hearing from you and thanks in advance.

Regards,

Doraintech
