A document must have exactly one root element exception on 5.1.0.2
upgrade.
Hey all,
Just upgraded to 5.1.0.2 and am getting this exception:
Caused by: org.apache.tapestry5.ioc.internal.util.TapestryException: A
document must have exactly one root element. Element <html> is already the
root element. [at classpath:com/inavero/pulse/pages/report/Edit.tml, line

Component works fine before upgrade but breaks after. Exception is on the
'writer.element("li")' line in beforeRenderBody. Here is the component

Thanks!

Ugh sorry about the poorly formatted question. It was one of those issues
that seemed so clear when I posted it but looking back there wasn't a good
amount of information. I figured it was merely an upgrade issue that I
wasnt aware of when moving to 5.1.
What was actually happening, for anyone else that might get this message,
was that I was calling element.close() one too many times. Normally I would
run into the 'you have rendered unbalanced elements' exception but it just
so happens that i was making sure that there werent any in my cleanup
method. The HTML element was actually being closed and LI elements were
being created after, hence the multiple root elements.
Anywho thanks for the suggestions guys, I provide more stripped down
snippets in the future :)

Anyone have a thought on this? I have no idea where to go from here.
