Oystein:
Just a thought, I have seen this error before, and generally (in my case) this has to do with the content. Particularly when combining smaller modular docs into a larger book or set. We use an ID="attribute" attribute for every section, sect1, sect2, etc. When combining sections if there are identical ID="attribute" usually something common like ID="introduction" that is when I see this error. Typically this error would not validate so it would surface well before the FOP step. However anything is possible. Are you are doing any transform to the data before running FOP? The fix is to use unique labels in the source attribute. Not always possible, but that is one possibility to look at. Hope it helps. /Gregorio -----Original Message----- From: Øystein Kleven <[email protected]> To: docbook-apps <[email protected]> Sent: Wed, Dec 11, 2013 12:32 pm Subject: [docbook-apps] How can I exclude an "index" page sequence from being processed by an xsl:when statement? Hi, Thanks to a previous post reply from Bob Stayton (https://lists.oasis-open.org/archives/docbook-apps/200804/msg00086.html), I have been able to build an article PDF doc with an index with multiple columns. However, this results in an FOP error: Property ID "xxxxx" (found on "fo:block") previously used; ID values must be unique within a document! After debugging, I have narrowed the problem down to the customization of the first xsl:when statement in the "footer.content" template in my custom stylesheet. (see below). If I remove that part (everything between "START" and "END" below), the FO processing succeeds, but the first page footer and the index footer (which is now also a "first" page in its separate page sequence) is of course incorrect, since the customization is missing. How can I keep the customization, but skip it when the page-sequence is handled as "index"? (I am (still) using DocBook 4.5 with XSL/FO version 1.73.2) Template excerpt: <xsl:template name="footer.content"> <xsl:param name="pageclass" select="''"/> <xsl:param name="sequence" select="''"/> <xsl:param name="position" select="''"/> <xsl:param name="gentext-key" select="''"/> <xsl:param name="master-reference" select="''"/> <fo:block> <xsl:choose> <!-- OKL: This includes/removes the footer content (not the rule line) from the first page (necessary for <article> docs) --> <!-- START --> <xsl:when test="$sequence = 'first'"> <xsl:choose> <xsl:when test="$double.sided = 0 and $position='left'"> <!-- <fo:page-number/> --> </xsl:when> <xsl:when test="$double.sided = 0 and $position = 'center'"> <fo:block text-align="justify"> <!-- OKL: Insert legal notice in the footer of the first page --> <xsl:apply-templates select="//legalnotice[1]" mode="article.titlepage.recto.auto.mode"/> </fo:block> </xsl:when> </xsl:choose> </xsl:when> <!-- END --> <xsl:when test="$pageclass = 'titlepage'"> <!-- nop; no footer on title pages --> </xsl:when> ................. </xsl:choose> </fo:block> </xsl:template> -- Regards, Øystein
