Build Identifier: 

See http://www.eclipse.org/forums/index.php?t=msg&th=166248&start=0& for message with formatting.

Following code causes exception.
It seems that by some reason "headerVisible" is trying to apply to TreeColumn instead of Tree itself.

Same code, with replacement of word "Tree" with "Table" works without any problem.

[code]<Shell xmlns="http://www.eclipse.org/xwt/presentation" xmlns:x="http://www.eclipse.org/xwt">
	<Shell.layout>
		<RowLayout/>
	</Shell.layout>
	<TreeViewer x:Style="BORDER">
		<TreeViewer.tree headerVisible="true" linesVisible="true">
			<TreeColumn text="New Column" width="100"/>
		</TreeViewer.tree>
	</TreeViewer>
</Shell>[/code]
