           Summary: Null Pointer exception in xsl mode
           Product: Fop
           Version: 0.20.5
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: general
        AssignedTo: fop-dev@xmlgraphics.apache.org
        ReportedBy: mark0978@yahoo.com


When your XSL file contains a condition that isn't met, so that you don't have a
<fo:root to do anything with you get a null pointer execption.

The xsl document looks like:
<xsl:stylesheet
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	xmlns:fo="http://www.w3.org/1999/XSL/Format"
	version="1.0">

    <xsl:template match="VWSEARCHRESULTS">
        <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">

---------
The xml document looks like 

<?xml version="1.0" encoding="utf-8" ?>
<VWSEARCHRESULT STATUS="success" XMLNS="https://test.valuewizard.com/webServices">
    <FAILUREDETAILS />
    <WARNINGDETAILS />

The problem is in the "match=" line in the template.  That "match=" statement
fails because there is a trailing S at the end of the word.  Rather than
reporting there is nothing to do, you get a Null pointer exception.

If you fill in well-formed XML you'll get a proper error message in the
maintenance branch and in the trunk. In the bug reporter's case however
the stylesheet produced non-wellformed output (the XML started with text
after the XML header). I've fixed the trunk to provide better error
messages.

Well, the bug report should read "no proper error message
if there is no fo:root". I vaguely remember Jeremias worked on
this, unfortunately I don't remember whether this got into
0.20.5, and I can't currently test it. Does someone else have
a 0.20.5 installation ready to run to do a quick test?
