[seabannan]

[ERROR] Script Error = 'undefined' is not a function (evaluating 'obj.otherwise()') (unknown file)
2012-08-20 09:15:29.483 socketio.titanium[4170:1b50b] *** Terminating app due to uncaught exception of class '__NSCFDictionary'
terminate called throwing an exception
[INFO] Application has exited from Simulator

Can someone tell me what this might be thanks

Hi.

I had a similar problem ( maybe the exact same problem ) when i tried the example app using the iPad simulator.

Turns out the IOS version is only included if You are running it on an iPhone.

Try changing the regex in the third line of the "Resources / socket.io-titanium.js" from /iphone/ to /iphone|ipad/ which will also match the iPad.

Hi Rene Thanks for the response

Can you please take me through setting up the environment to work for me i am doing the following.

i have installed node http://nodejs.org/ with the package manager so i have node and npm installed correctly then i import your github project into titanium so i have all the files their.

i cd into to example-nodejs-server

cd example-nodejs-server/

then i run the command to fire up the node server with socket.io

node chat.js

and i get the following output

module.js:340
    throw err;
          ^

Hi Rene

I know have this fired up and it is working on the mobile devices, but i am getting this through the browser.

XMLHttpRequest cannot load http://127.0.0.1:8080/socket.io/1/?t=1345803254195. Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true.

sorry to keep commenting

just thought it my be handy for anyone who is trying to get this working

The output of the chat.js node server is

handshake authorized 1459053066821082569

Any help on this thanks

[renelaerke]

I had some strange problems to. I decided to rename (alternetively delete) the node_modules directory in the chat example directory.

It turns out that thèrese might be a versioning problem somewhere.

Nevermind - when i removed the node_modules node will use any global modules instead. Now my setup works just fine.

Btw I'm new to node development so you should consider any advice i can give you carefully beboer implementing.

Did you now about the nodecasts.net? Checkout these no frill node screencasts http://nodecasts.net/
