hx:scriptCollector

I was having a problem where the included exception would be thrown,
only to find out it was because an hx:scriptCollector tag was being
added at the after the beginning <body> tag and right before the end of
the </body> tag.  If I take it out my JSF app runs just fine.  Anyone
know why this is causing the error?

Thanks,
Aaron Bartell
