This is a known bug with the way woven handles generating subwidgets -- 
I haven't decided what a satisfactory solution is yet. I'll think about 
it today. Generally, my solution is to not do too much work in a single 
Widget -- just apply separate view= attributes to nodes inside of nodes 
and let each Widget handle a single level of DOM nodes.

I think I have a simple solution that will make the above use case work 
properly, though. I'll write a test for it and see if I can get the 
solution checked in today. Thanks for the code.
