Cross-ref inconsistencies in FM6 and PDF

["Michael Lewis" <mlewis@xxxxxxxxxxxxxx>]

Framers all,

This is for info. I've just had an interesting experience that I haven't
seen reported previously. (Apologies if I've missed it.)

Client has a junior tech writer, fairly new to FM. She was given the task of
restructuring an existing multi-file FM doc (essentially 1 file per chapter,
plus front matter and ToC). This involved changing some headings, either in
wording or in pgf tag (Heading 3 changing to Heading 2, etc).

I was asked to investigate the fact that some crossref links in the
generated PDF didn't work. Acrobat knew they were links (cursor changed to
pointing finger, whole xref flashed when clicked) but they didn't go
anywhere.

It turned out that all such xrefs linked to a changed heading. It's not
altogether surprising that, if you change the text at the source of a
crossref, something might happen to the generated link. What I was really
puzzled by was that the xrefs were fine in the FM files ("Go to source"
worked), FM didn't complain when the book was updated, and the PDF
generation process didn't raise any warnings or errors. We just finished up
with non-functional links.

Of course, creating fresh xrefs in FM and regenerating the PDF fixed the
problem.
