On an older version of the toolkit we used onErrorcallbacks. I cannot find such callbacks in the DaSubscription/item/session. Is there a way to check if items exist on the OPC server?
Assuming an item exists and will be deleted on the server while the client is running how would you catch and handle the error? Is there a callback for such an error?
