EventSocket Exception on Stream Enabled "null" Value

[wooliet]

zetta/lib/event_socket.js

EventSocket.prototype.send = function(topic, data) {
  if (!Buffer.isBuffer(data) && typeof data === 'object') {
    var tmpData = (this.streamEnabled) ? data.data : data;

    if (tmpData['transitions']) {

Error: "Cannot read property 'transitions' of null"

I have a monitorable property "delay" that is typically a decrementing number. It can be set to null though, and when it does, the above exception occurs (while events socket is open).

Thanks @wooliet i found the error and should have a fix by end of day.

What do you expect the client to see when the value goes null?

[wooliet]

null I suppose. Is that not an expected use case?
