[xwiki-users] Broken PDF export

Thu Aug 31 21:28:24 CEST 2006

Hi,

For PDF export the first thing to check is if you can export an empty or 
near empty document
If not then you probably have a setup problem (temp dir, etc..)
If yes, then it has to do with the content

Known problems are:

- PDF export does not always support custom HTML. HTML easily breaks the 
export
- PDF export refuses to have to subtitles with the same name. Currently 
it generates anchors with the same ID which is non valid HTML and breaks 
the PDF export

Somebody is actually working to fix this issue in the anchor ID generation

Concerning non latin issues, I'm not sure I'm a good help  !
