Re: DOMWrite an HTMLDocument

Hi Jake,

Thanks a lot for the workaround. Unfortunatly it doesn't work for me 
because my Document comes from an XSL transformation, so it is not a 
class. I'm using it to generate a preview:
http://www.livesidebar.com/servlet/SetTheme.event?themeId=doubleTab

Fortunatly, it works for XML Documents, so I'm now generating XHTML 
which is fine for now. Hopefully this bug will be fixed when I need to 
generate HTML again, so that's fine :)

Thanks again!
Cheers,
Roger.
