Ok... my mistake.

I do some sorting later on in the pipeline which sorts the rows based on it's
contents.

Sorry about this.
Robby

Hi Andrew,

I'm using Saxon8.7 for my projects.  It's also the default version of Saxon
used with Apache Cocoon2.2 and I've been using it for the last 2 years.

I wrote a little simplified version

<xsl:copy-of select="for $i in (1 to $rowSize) return nxp:getRow($i)"/>

  <xsl:function name="nxp:getRow">
    <xsl:param name="rowIndex"/>
    <row rowIndex="{$rowIndex}"/>
  </xsl:function>

Which produces  correctly
<tbody>
   <row rowIndex="1"/>
   <row rowIndex="2"/>
   <row rowIndex="3"/>
   <row rowIndex="4"/>
   <row rowIndex="5"/>
</tbody>

The only difference I see is that I pass on multiple function arguments AND I
reference globally declared variables in this function (closure).  Could the
last be messing up execution order somehow?

I'm willing to create a similar simplified setup and try if I can reproduce a
similar issue.

removing all of the irrelevant code, that simplifies down to:

<xsl:function name="nxp:getPinningTableRow">
  <xsl:param name="rowIndex"/>
  <row rowIndex="{$rowIndex}"/>
</xsl:function>

<xsl:template match="/">
  <tbody>
    <xsl:copy-of select="for $i in (1 to 5) return
nxp:getPinningTableRow($i)"/>
  </tbody>
</xsl:template>

which outputs:

<tbody>
   <row rowIndex="1"/>
   <row rowIndex="2"/>
   <row rowIndex="3"/>
   <row rowIndex="4"/>
   <row rowIndex="5"/>
</tbody>

using Saxon 9.1.0.3

If you get something different with the above, post back with your set up.

cheers
andrew
