Internal links in footnotes cause PDF generation to fail

[pdc@…]

[jira2trac import : issue created on January 6, 2009 11:10:55 PM CET ​http://issues.cocoondev.org/browse/DSY-687 ]

If a footnote (i.e., in a <span class="footnote">) contains a link to another doc in the same site, a request for a PDF of the doc with the footnote in it results in the following error:
Failed to process pipeline
Error(Unknown location): fo:footnote is not a valid child element of fo:block.

This happens both when a Daisy link is used and when a full URL is used.

It does not happen, however, if there is a link in a footnote to another site. (I've only tested that with non-Daisy sites.)

I can reproduce this, but it always occurs (even in the last case)

Here's what goes wrong:

Currently, when you create a link (outsite of a footnote), a footnote is created containing the URL (so that people using the printed PDF can still know where the link points to).
When you create a link inside a footnote, the PDF version would need to contain a footnote-in-footnote. That's where the invalid xslfo is generated (fo:footnote in fo:block)

I can't think of a workaround (except not using links inside footnotes)

Thanks for the explanation. And I can now correct what I said about the error not happening if the link is to another site: The error does not happen if there is a hyperlinked URL in a footnote.
