onDisconnect issue

[tdalianis]

Hi,
In my program I dynamically add and remove kevoree nodes (docker containers) all attached in the same group.

In order for the deletions to be depicted in the kevoree editor I use in my kev script the command set sync.onDisconnect = 'remove {nodeName}'.

The issue is that when the first deletion occurs, I get the following error in the master node. It seems that there is a reference to the node removed and this is causing a null pointer exception. Actually both communication channels (masterToObserver, observerToMaster) throw similar exceptions.

02:27 INFO: master sending message to observers:{"nodeSubType":"SentimentProcessor","action":"addNode","node":{"host":"10.10.10.197","nodeType":"processor","nodeSubType":"SentimentProcessor","nodeName":"SentimentProcessor_7","containerID":"SentimentProcessor_7"}}
