Uncaught Type Error when using Titanium Alloy models

Question

I am using Titanium alloy models, most of the code I extracted from sample

https://github.com/appcelerator/alloy/tree/master/samples/todo

When I tried to compile my project I got this error.

I am using Titanium 3.1.2, Alloy 1.2.2

Answer 1

Had figured out the issue. I had not added the collection in the markup.

Adding <Collection src="note"/> as first child of alloy solved the issue.
