Thanks Giuseppe for the reply,

I have another question in command mode subscription mode,

Consider my data feed is from DB/REST call,
In subscribe method data retrieval fails for client 1, because of datasource DB/REST API server issue.

After some time client 2 connects, in this scenario i am noticing that subscribe method is never called untill there are atleast one active subscription for that item.

Here the scenario is the snapshot data is not sent to server from feed, so the consecutive client connections must some how trigger the subscribe method or data retrieval logic to give the data.


How to mitigate this call, i tried throwing the SubscriptionException,FailureException but i am not seeing any effect. There is no call made to adapter upon second connection.

Thanks
