Glad to hear, Blair i fixed it by using the data service in the app builder, not in the API express module (i used a where just like normal rest service - Jquery app).
Evgene, best thing would be if we can import view's or query's straight from dataserver instead of re-writing it in API express (but maybe that's nice to have for the future ?), i now need my data back in a list so am back at the query problem..
but will wait for your reply in original topic.
