Hi all,

I'm using JavaScript / HTML as the client, with a Java Lightstreamer adapter serving the data.

The problem I am encountering is that whenever I attempt to subscribe to an item, and specify a field on that item that doesn't exist, subsequent subscriptions all seem to fail silently. How do I know they're failing? Because my subscription listener returns null for every fieldValue that is returned. It does this once, after the subscription is made, and then never again does that listener receive data updates despite the item changing!

I am wondering a basic question:

Does attempting to create a Subscription with invalid fields, break lightstreamer? By invalid fields, I mean fields that do not exist on the item.

Any help would be great!
