Hi Ren, each call is related with an http-request. I would try to minimize the number of http-requests (e.g. GWT-RPC)
When an event causes multiple subrequests, it is a good idea to collect them and deliver them with a single http-request, However, your service interface must be able to do so. On the other side, your example sound strange. Your security should not depend on client behaviour. When a data item should not be seen by a certain user, you should not send it to the client at all.
