Misunderstand output from fop

[Petr Hracek <petr.hracek@siemens.com>]

Hello all,

when I want to convert xml->pdf then from fop I have received following 
messages.
Do you know where can be problem?


[ERROR] Error in column-width property value '1%': 
org.apache.fop.fo.expr.PropertyException: No conversion defined
[ERROR] Error in column-width property value '1%':

[ERROR] Error building hyphenation tree for language cs

In the header of book I have:
<book lang=cs>

I am using fop 0.20.5.
Xsltproc (Fedora Core 4) work fine any all converts OK.
Commands for conversion are following:

#!/bin/bash
xsltproc -o DenikZaslOtce.fo DenikZaslOtce.xsl DenikZaslOtce.xml
fop-0.20.5/fop.sh -c fop-0.20.5/conf/userconfig.xml -fo DenikZaslOtce.fo 
-pdf DenikZaslOtce.pdf

Do you know where can I have problem?
regards
