I have two subscriptions to the same collection, they are using different publications. One contains a certain field, the other does not. I noticed that in effect, that particular field is not available on the client side, even on documents that match the publication that includes that field. I expected that fields would be merged, so a superset of all fields will be received? And I am pretty sure this worked a while ago. Only if a third publication kicks in that contains all fields again (a detail dialog), the other publication receives its data.
Resolved. There was a problem in the query logic.
