List of figures appears empty in PDF file

Greetings,

I would like to have a list of figures in the print output for my book project.

I have set the following in fo/params.xls:

<!-- 3. ToC/LoT/Index Generation ================================ -->
<xsl:param name="autotoc.label.separator" select="' '"/>
<xsl:param name="generate.toc">
/article  toc,title
article   toc,title
book      toc,title,figure
part      toc,title
reference toc,title
set       toc,title
</xsl:param>
<xsl:param name="toc.indent.width">1</xsl:param>

Now, I run fop and interestingly this is what I get:

Making portrait pages on A4 paper (210mmx297mm)
height is now: 297
unit is now: mm
goldenratio: 1.618/>
blockHeight is: 113.454
tableWidth is: 187.5
cellHeight is: 123.75
