null pointer exception in Saxon
I'm using the extension functions in Saxon to integrate a Java Hashtable
into a stylesheet, but get a null point exception when testing a null value.
The stylesheet is setup as follows:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:hashtable="/java.util.Hashtable"
xmlns:saxon="http://icl.com/saxon"
extension-element-prefix="saxon"
version="1.0" >
<xsl:variable name="lookup" select="hashtable:new()"/>
in a template, it test this:
<xsl:if test="hashtable:get($lookup, @name)">
But, if the hashtable key is not present in the hashtable, Saxon throws a
null pointer exception. I would expect the expression in the xsl:if
statement to return false. In any case, the null should be caught. (I'm
using Saxon version 5.3.2).
