Circular variable/parameter reference if recursive template is used in global
variable
--------------------------------------------------------------------------------------
Key: XALANJ-2430
URL: https://issues.apache.org/jira/browse/XALANJ-2430
Project: XalanJ2
Issue Type: Bug
Components: XSLTC
Affects Versions: 2.7.1
Environment: Ubuntu 7.10, java-1.5.0-sun-1.5.0.13, Xalan 2.7.1, Xerces
2.9.0 (from Xalan package)
Reporter: Auke Schrijnen
Xalan 2.7.1 won't compile an xslt when a recursive template is used in a global
variable. This works in Xalan 2.7.0!
2.7.1 throws a TransformerException: Circular variable/parameter reference in
'[variable(countInfo)]'.
Example:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version='1.0'>
<xsl:template name='countRecursive'>
<xsl:param name='info'/>
<xsl:param name='count' select='"1"'/>
<xsl:choose>
<xsl:when test='$info != "" and number($count) < 4'>
<xsl:call-template name='countRecursive'>
<xsl:with-param name='info' select='substring-after($info, "
")'/>
<xsl:with-param name='count' select='$count + 1'/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select='$count'/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:variable name='countInfo'>
<xsl:variable name='someElement'>
<xsl:value-of select='/root/vars'/>
</xsl:variable>
<xsl:call-template name='countRecursive'>
<xsl:with-param name='info' select='$someElement'/>
</xsl:call-template>
</xsl:variable>
<xsl:template match='/'>
<xsl:element name='count'>
<xsl:value-of select='$countInfo'/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
