Subject Re: Odd Behavior with HSSFSerializer
Date Wed, 25 Jun 2008 16:05:56 GMT
I had the same problem. I fixed it like this:

Style regions are built for each column for max 999 rows.
Larger regions do not seem to work.
That's why styles template is called more then once if number of rows  
to print exceedes 999.
<xsl:template name="styles">
	<xsl:param name="startRow"/>
	<xsl:param name="size"/>
	<xsl:variable name="endRow">
			<xsl:when test="($size - $startRow) &gt; 999"><xsl:value-of  
select="$startRow + 998"/></xsl:when>
			<xsl:otherwise><xsl:value-of select="$size"/></xsl:otherwise>
		<StyleRegion ...">
			<xsl:attribute name="startRow"><xsl:value-of select="$startRow"/></ 
			<xsl:attribute name="endRow"><xsl:value-of select="$endRow"/></ 
			<Style ...>
	<xsl:if test="($size - $startRow) &gt; 999">
		<xsl:call-template name="styles">
			<xsl:with-param name="startRow"><xsl:value-of select="$startRow +  
			<xsl:with-param name="size"><xsl:value-of select="$size"/></ 

The template is called for the first time with:

<xsl:call-template name="styles">
	<xsl:with-param name="startRow">1</xsl:with-param>
	<xsl:with-param name="size">total-nr-of-elements</xsl:with-param>
