TypeError: Cannot set property 'with' of undefined

I can connect successfully on my asterisk with node-asterisk, but when I get the Dial event, the app crashes with the following message (using asterisk 1.6.x) :

    $ node test.js 
    CLIENT: Connected!
     CLIENT: Logged in!

     /opt/node-asterisk/asterisk.js:125
            self.participants[headers.srcuniqueid]['with'] = headers.destuniqueid;
                                                        ^
     TypeError: Cannot set property 'with' of undefined

I noticed the same thing last night. I think the updates to node.js has caused this.

er - I just realized that this was tested on 1.4.x. 1.6.x changed stuff in the manager.

I am also facing these problem i don't know how to resolve this problem ? if any event recieve then nodejs server suddenly terminate why ?

Thanks
