I am using 0.92beta, using xslt to PDF.

Most of time the generation works fine, but sometimes it throw exception as
following, it seems some class is not thread safe:

; SystemID:
file:///usr/bea/home/beadtp4/config/dp4/tecp/config/conf/fop/fax-mail.xsl;
Line#: 66; Column#: 93
javax.xml.transform.TransformerException:
java.lang.IllegalArgumentException: The number of this PDFNumber must not be
empty

        at
org.apache.xalan.transformer.TransformerImpl.transformNode(TransformerImpl.java:1213)


The line reported wrong in xsl is :
                        <fo:page-sequence master-reference="Section1-ps" >


The code is complicate and confidential, so sorry I can not attach here, but
this seems strange, i need some idea how can this happen sometime and not
always...

Thanks
Michael
