Multiple subscriptions in batch mode

Hi all, I created multiple notifications using idPattern (Car[1-5]) to sent notifications for any Cars of the same type to save data using Cygnus. Subscriptions works! I can update any attribute (i.e. /v2/entities/Car1/attrs/speed). But can I use a batch operation (v2/op/update) to update multiple attrs? I tried but only one (first) attribute will be notified (and stored) If yes, what can I do it? I also tried to configure CYGNUSMYSQLBATCH_xxx params but without success. Thank you pasquy

The subscriptions have a field to "narrow down" the notifications, only including those attributes that the subscription "asks to be included". Perhaps this is why you get only the first attribute in the notifications. If this is not the case, then it may be a bug in Orion. If you feel that it is a bug, the way to go is to report it as an issue on Orion's github - https://github.com/telefonicaid/fiwar..., giving a complete description of the problem, including all details, e.g. the exact payload body and headers that was used when creating the subscriptions, same same for the batch update operation. Also, version of the broker (output from GET /version) and anything else you feel might be useful to reproduce the problem.

Singular notifications (/v2/entities/Car1/attrs/speed and /v2/entities/Car2/attrs/speed) are fine. Of course, I'm using the same headers (for all). But only the first entity (Car1) will be notified if I change the speed attribute for both, using /v2/op/update API.
