Description

I have cases where I want to use only one single model for tableView data binding as below - one model for multiple rows...

<Alloy>
	<Model src="adidas"/>
	<Window fullscreen="true" backgroundColor="white">
		<TableView>
			<TableViewRow title="{adidas.name}" />
			<TableViewRow title="{adidas.host_organization}" />
			<TableViewRow title="{adidas.id}" />
		</TableView>
	</Window>
</Alloy>

var adidas = Alloy.Models.instance("adidas");

adidas.fetch({
	"id" : 39
});
$.index.open();

See the attached screen dump that shows the result I wish to see However, the code snippet above crashes the app probably because such kind of way of data binding has not supported yet in Alloy - see error log

Not sure if binding this way makes sense or not, but it is really useful in my case.
