Bug clearing and replacing observable used in an Each and Deferred

Bug Reports
1

I have found a bug whereby elements inside an Each that are marked as Deferred are not removed even if the Observable is cleared or replaceAll is invoked. If you remove the Deferred inside the Each replaceAll and clear work correctly. For the time being I will just not use Deferred when I need to dynamically update and clear the underlying observable array.

An example project is available : https://drive.google.com/file/d/0Byxe7r1yoUiDT2UxaHJJb3A3aUE/view?usp=sharing

The bug can be replicated on version 0.25 and version 0.26

<StackPanel>
	<Each Items="{searchResults}">
		<!-- REMOVE THE DEFERRED TO HAVE DESIRED FUNCTIONALITY OF CLEAR AND REPLACEALL -->
		<Deferred>
			<Grid Columns="auto,1*" Background="#fff">
				<Panel>
					<Image Width="100" Height="100" StretchMode="UniformToFill" Url="{Icon.URL}" />
				</Panel>
				<Panel>
					<StackPanel Alignment="VerticalCenter" Padding="10,0,0,0">
						<Panel>
							<Text Value="{Text}" TextWrapping="Wrap" FontSize="13" TextColor="#888" />
						</Panel>
					</StackPanel>
				</Panel>
			</Grid>
			<Panel Alignment="VerticalCenter">
				<Rectangle Height="1" Fill="#dcdee3" />
			</Panel>
		</Deferred>
	</Each>
</StackPanel>

The following methods do not work if the Each element is wrapped in Deferred

searchResults.clear();
searchResults.replaceAll(newArray);

Hi,

Thanks for reporting. I believe this bug has already been fixed internally but not yet rolled out.

You can fix it by wrapping the Deferred in yet another Panel. Let us know if the problem persists in a later version (0.27+).
