I get and StackOverflow error when using normalize-space for a given

sounds like a endless recursion or something like that. Has somebody
experience a similar problem?
It is not a good idea to base a post to the list on wild
guessing.
For a start, FOP does not implement any funnction called
normalize-space, this is XSLT functionality. Whether the
stack overflow is caused by the XSLT processor or by FOP
or whether there is a causal link between using the function
and the error is anyones guess.
Advice for tracking down the problem:
1. Run the XSLT standalone (have a look into the FOP docs
for hints). This will tell you whether the problem is
in your XSLT and/or the XSLT processor or whether it
is FOP. If it was the XSLT, track down which processor
you use and ask there.
2. If there isn't anything remarkable in the transformation,
feed the result into FOP. If an error occurs, run it again
with the -d flag. If the error suddenly disappeared, check
whether you used disable-output-escaping or indent=yes
in the XSLT.
3. If you ask on the list, include
- the FOP release number
- the JDK release
- the OS/platform, unless it's windows
- whether you run FOP from the command line or embedded
- if an exception occurs, the first lines of the stack trace
up to the second or third line containing apache (snip
the rest)
- state the facts, refrain from guessing causes; you're
most probably wrong anyway
4. Include a small, self-contained and well formatted FO file
which demonstrates the problem.
