Description

The sample app * https://github.com/appcelerator/alloy/tree/master/test/apps/models/binding_no_persistence fails with the error * TypeError: Cannot read property '__transform' of undefined (Android) and * TypeError: undefined is not an object (evaluating '$model.__transform') (iOS) respectively. Does this mean that it is no more possible to use Alloy Binding without persistence?

Hello, I can't access the sample app page. Can you attach the file in here for us to test? Thanks.

I think I didn't add the link properly, sorry. Try this: [https://github.com/appcelerator/alloy/tree/master/samples/apps/models/binding_no_persistence] I also added the sample in question as a zip file.

[~twiesen], binding without persistence still works. You just need to create the model files under app/models with no adapter type. E.g.

   // app/models/appState.js
   exports.definition = {
   	config: {
   		"defaults": {
   			counter: 1,
   			color: '#00f'
   		}
   	},
   	extendCollection : function(Collection) {
   		_.extend(Collection.prototype, {
   
   			// For Backbone v1.1.2, uncomment this to override the fetch method
   			/*
   			fetch: function(options) {
   				options = options ? _.clone(options) : {};
   				options.reset = true;
   				return Backbone.Collection.prototype.fetch.call(this, options);
   			},
   			*/
   		});
   		return Collection;
   	}
   }

Thank you so much! I wasn't aware of this change and I couldn't find it documented anywhere.
