Gordon, Generally, having CQ on thin client would definitely be awesome. My only point is that thin client has several technical limitations that would introduce multiple "ifs" into the functionality. What exactly those ifs are, and weather there is still value with all those ifs, is a big questio

Igor, I just think that we're dealing with a trade off here, and that if we implement CQ for thin client, we will either end with a client that is not "thin" anymore, or semantics and guarantees of CQ would change so drastically that it would be a completely different feature. Either way, it's a b

Guys, Personally, I do not see any problems, why we can not implement Continuous Queries for thin clients. This will require a decent amount of work, and will not give such strong guaranties as thick clients give (for example, on server crash thin client will get an exception and will need to re-
