I'd like to combine a listviewer and a datatrigger:

<Text x:Style="BORDER" x:Name="textAge" text="{Binding ElementName=listViewer,
path=singleSelection.(y:Employee.age), UpdateSourceTrigger=PropertyChanged}">
		<Text.triggers>
			<DataTrigger binding="{Binding path=singleSelection.(y:Employee.age)}" value="10" operator="GT">
				<Setter property="background" value="red" />
			</DataTrigger>
		</Text.triggers>
</Text>

When I try the above Code I get the following exception:

java.lang.NullPointerException
	at org.eclipse.e4.xwt.core.DataTrigger.on(DataTrigger.java:222)

Just a guess: The exception might be thrown because at program start nothing is selected in the listviewer?

Reproducible: Always
