Description

When using the following code inside an Alloy view, the Alloy compiler will crash: Code:

<Alloy>
	<Window>
		<ListView>
			<Templates>
				<ItemTemplate name="TabbedItem">
					<Label class="title" bindid="title"/>
					<TabbedBar platform="ios" bindId="tabs">
			                	<Labels>
			               			<Label class="test1">Label 1</Label>
			                		<Label class="test2">Label 2</Label>
			            		</Labels>
			        	</TabbedBar>
				</ItemTemplate>
			</Templates>
			<ListSection>
				<ListItem template="TabbedItem" tabs:index="0" />
			</ListSection>
		</ListView>
	</Window>
</Alloy>

[~fmiao] Which fix-version should this fix go into?
Wilson Luu 2016-12-09

Closing ticket as fixed. Verified that if I use the above Alloy view code, then I do not get the TypeError: Cannot read property 'symbol' of undefined when I use appc run. Also, verified that I get the error when I compile the Alloy view with alloy@1.9.2. Tested on: Appc CLI NPM: 4.2.8 Appc CLI Core: 6.1.0-312 Alloy: 1.9.5 Arrow: 1.10.0-19 SDK: 6.0.0.GA Node: v4.6.2 OS: Mac OS X (10.12.1) Xcode: 8.1 Devices: iphone 7 plus simulator (10.1)
