Re: onError from image request inbox lost
Hi Samtoggle quoted messageShow quoted text
I have been looking at a similar issue with snapshot subscriptions on our TREP bridge. The problem is a bit more general in that it includes conditions such as handling a bad symbol name but nevertheless the problem is how to notify on a callback.
I don't have any answers at the moment as I haven't been able to allocate any time to it but I had kind of assumed that there should be a way of calling the mamaSubscription OnError callback.
It would be interesting to know what mama client applications expect to happen and also what does the wmw bridge do in this situation

Subject: [Openmama-dev] onError from image request inbox lost
I've got a (hopefully) quick question for you guys.
First off, our scenario: instead of getting initials and recaps from an interactive publisher, our middleware bridge allows market data subscribers to get initials/recaps from a cache. The cache can report a condition where there is no data for a particular subject, and we'd like to give that information to applications. Currently our bridge does nothing in this case, and eventually the image request times out.
Now my question: I'm attempting to deliver an onError from the inbox of an image request in a market data subscription to the application, but the image request does not provide an onError callback to the subscription. (See http://tinyurl.com/ld8cwfh) Is this intentional, or would it make sense to pass the onError callback through? If passing the onError through is correct, what is the right way to handle the destroy handle?
