Re: [docbook-apps] <qandaset defaultlabel="none"> FOP error

Hi Eric,

Indeed, this is a bug in the template with match="question" in 
fo/qandaset.xsl.  I've fixed it in SVN for the next release, and you can 
use this version in your customization layer:

 

<xsl:template match="question">
  
<xsl:variable name="id"><xsl:call-template 
name="object.id"/></xsl:variable>

 

  <xsl:variable 
name="entry.id">
    <xsl:call-template 
name="object.id">
      <xsl:with-param 
name="object" select="parent::*"/>
    
</xsl:call-template>
  </xsl:variable>

 

  <xsl:variable 
name="deflabel">
    <xsl:apply-templates select="." 
mode="qanda.defaultlabel"/>
  </xsl:variable>

 

  <xsl:variable name="label.content">
    
<xsl:apply-templates select="." 
mode="label.markup"/>
    <xsl:if 
test="contains($deflabel, 'number') and 
not(label)">
      <xsl:apply-templates 
select="." mode="intralabel.punctuation"/>
    
</xsl:if>
  </xsl:variable>

 

  <fo:list-item id="{$entry.id}" 
xsl:use-attribute-sets="list.item.spacing">
    
<fo:list-item-label id="{$id}" 
end-indent="label-end()">
      
<xsl:choose>
        <xsl:when 
test="string-length($label.content) &gt; 
0">
          <fo:block 
font-weight="bold">
            
<xsl:copy-of 
select="$label.content"/>
          
</fo:block>
        
</xsl:when>
        
<xsl:otherwise>
          
<fo:block/>
        
</xsl:otherwise>
      
</xsl:choose>
    
</fo:list-item-label>
    <fo:list-item-body 
start-indent="body-start()">
      
<xsl:choose>
        <xsl:when 
test="$deflabel = 'none' and 
not(label)">
          
<fo:block 
font-weight="bold">
            
<xsl:apply-templates 
select="*[local-name(.)!='label']"/>
          
</fo:block>
        
</xsl:when>
        
<xsl:otherwise>
          
<xsl:apply-templates 
select="*[local-name(.)!='label']"/>
        
</xsl:otherwise>
      
</xsl:choose>
      <!-- Uncomment this 
line to get revhistory output in the question 
-->
      <!-- <xsl:apply-templates 
select="preceding-sibling::revhistory"/> -->
    
</fo:list-item-body>
  
</fo:list-item>
</xsl:template>

Subject: [docbook-apps] <qandaset defaultlabel="none"> FOP 
error

Hello, I?m unable to build a PDF from a docbook 4 document 
that has a <qandaset defaultlabel=?none?> tag in it. If I remove the 
attribute, everything works fine. If I leave it in, I get the following 
errors:

 

The 
process 'Apache FOP' ended with code: 1.

The 
error was: 

ERROR - Couldn't find 
hyphenation pattern for lang="en".

Is this a known bug? I?m not sure whether the problem is with 
docbook-xsl or fop. Is ther a workaround for this that doesn?t involve changing 
my XML source code?
