From 2debfc561d3ad517ad0c82ebd18cba8ec78ab6ce Mon Sep 17 00:00:00 2001 From: Jonathan Aillet Date: Fri, 2 Mar 2018 11:51:42 +0100 Subject: Change subscribed signals search to check filters as well When a new subscription is made, search in existing subscription for a combination of a signal and a filter instead of searching for just a signal. In this way, each subscription will receive signals according to their requesting filter.
