Multiple Selections of a Node--Appears to be a Bug

[Renick, Garrel]

I'm seeing different results of a simple transformation using
xalan-j_2_6_0 (and prior versions) versus xalan-j_2_7_0. This happens on
BSD and Windows implementations. The xalan-j_2_7_0 version results in
duplicated output as described below. I'm using jdk1.5.0_12. Here is a
data set and a stylesheet that display the problem:

 

XML:

<?xml version='1.0'?>

<document>

 <permission>

  <grp gid="101" name="group1"/>

  <grp gid="102" name="group2"/>

 </permission>

</document>

 

XSLT:

<?xml version="1.0"?>

<xsl:stylesheet  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";

version="1.0">

  <xsl:output  method="html"/>

 

  <xsl:variable name="theData" select="/document/permission"/>

 

  <xsl:template match="/document">

    <xsl:variable name="grpcount"  select="count($theData/grp)"/> 

    <xsl:call-template name="makeGroupList">

      <xsl:with-param name="groupSize" select="$grpcount"/>

    </xsl:call-template>

  </xsl:template>

  

  <xsl:template name="makeGroupList">

    <xsl:param name="groupSize"/>

    <select name="selectName" size="{$groupSize}" multiple="true">

      <xsl:apply-templates select="$theData/grp">

        <xsl:sort select="@name"/>

      </xsl:apply-templates>

    </select>

  </xsl:template>

 

  <xsl:template match="grp">

    <xsl:variable name="gid" select="./@gid"/>

        <option value="{$gid}"><xsl:value-of select="@name"/></option>

  </xsl:template>

</xsl:stylesheet>

 

Output xalan-j_2_7_0:

<select multiple="true" size="2" name="selectName">

  <option value="101">group1</option>

  <option value="101">group1</option>

  <option value="102">group2</option>

  <option value="102">group2</option>

</select>

 

However, the output from j_2_6_0 (and earlier versions) is as expected:

 

Output xalan-j_2_6_0:

<select multiple="true" size="2" name="selectName">

  <option value="101">group1</option>

  <option value="102">group2</option>

</select>

 

If I comment out the grpcount variable definition and pass a param with
a literal value in the call to the makeGroupList template, both versions
of xalan produce the same output.

 

I'd appreciate any insight into why this is happening.
