Error: Circular definition of variable ...

[phranck]

Hi there!

In an XSL I have the following lines of code:

Code: Select all

  <xsl:variable name="hasSecondPage">

    <xsl:choose>

      <xsl:when test="$numberOfRounds = $numberOfRoundsToDisplayOnFirstPage and $numberOfRounds > $maxNumberOfRoundsOnFirstPage">

        <xsl:value-of select="true()"/>

      </xsl:when>

      <xsl:when test="($numberOfRoundsToDisplayOnFirstPage < ($numberOfRounds + 1)) and ($numberOfRounds != $numberOfRoundsToDisplayOnFirstPage)">

        <xsl:value-of select="true()"/>

      </xsl:when>

      <xsl:otherwise>

        <xsl:value-of select="false()"/>

      </xsl:otherwise>

    </xsl:choose>

  </xsl:variable>



  <xsl:variable name="numberOfRoundsToDisplayOnFirstPage" as="xs:integer">

    <xsl:variable name="rounds" select="/tourmatchesreport/tourmatchesreportitem/numberOfRoundsToDisplayOnFirstPage" as="xs:integer"/>

    <xsl:choose>

      <xsl:when test="$hasSecondPage = true()">

        <xsl:value-of select="$rounds"/>

      </xsl:when>

      <xsl:otherwise>

        <xsl:value-of select="$rounds + 1"/>

      </xsl:otherwise>

    </xsl:choose>

  </xsl:variable>

If I do a transformation with the related XML this error occurs:

Code: Select all

SystemID: ~/Developer/theLeague/TennisFramework/tournamentMatchesReportRaster64.xsl

Description: Circular definition of variable hasSecondPage

The confusing thing is, if I change the definition of the variable 'numberOfRoundsToDisplayOnFirstPage' to the following code, everything is fine:

Code: Select all

<xsl:variable name="numberOfRoundsToDisplayOnFirstPage" select="/tourmatchesreport/tourmatchesreportitem/numberOfRoundsToDisplayOnFirstPage" as="xs:integer" />

What is wrong here?

Thanks for your help,
phranck

Hello,

The variable hasSecondPage was defined based on the variable numberOfRoundsToDisplayOnFirstPage which was defined based on hasSecondPage. This is a circular definition because the definition of hasSecondPage is based on itself. A definition in which the value of a variable is based on the value of the same variable is not allowed in XSLT.
