Property id is unique but FOP 0.91 reports an error.
Hi,
I have the master set:
<fo:layout-master-set>
<fo:simple-page-master margin-bottom="0mm"
margin-top="0mm" margin-right="1cm" margin-left="8mm"
page-height="297mm" page-width="210mm" master-name="first-page">
<fo:region-body margin-left="12mm"
margin-top="120mm" margin-bottom="43.5mm"/>
<fo:region-before extent="120mm"
region-name="xsl-region-before-1"/>
<fo:region-after
region-name="xsl-region-after-1" extent="41mm"/>
</fo:simple-page-master>
<fo:simple-page-master margin-bottom="0mm"
margin-top="0mm" margin-right="1cm" margin-left="8mm"
page-height="297mm" page-width="210mm" master-name="others">
<fo:region-body margin-left="12mm"
margin-top="105mm" margin-bottom="43.5mm"/>
<fo:region-before extent="105mm"
region-name="xsl-region-before-2"/>
<fo:region-after
region-name="xsl-region-after-1" extent="41mm"/>
</fo:simple-page-master>
<fo:page-sequence-master master-name="standard">
<fo:repeatable-page-master-alternatives>
<fo:conditional-page-master-reference
master-reference="first-page" page-position="first"/>
<fo:conditional-page-master-reference
master-reference="others" page-position="rest"/>
</fo:repeatable-page-master-alternatives>
</fo:page-sequence-master>
</fo:layout-master-set>
There is a reference
<fo:page-number/>/<fo:page-number-citation ref-id="lastPage"/>
inside xsl-region-before-1 (1st page) and xsl-region-before-2 (others)
to a unique id="lastPage".
"lastPage" is only once defined in <fo:root>
.....
</fo:table>
</fo:block>
<fo:block id="lastPage"/>
</fo:flow>
</fo:page-sequence>
</fo:root>
FOP 0.91 tells me "org.apache.fop.fo.ValidationException: null:15463:26:
Property id "lastPage" previously used; id values must be unique in
document." for every pdf document that has more than 1 page.
Is this an bug issue?

Joachim Unger

Joachim,
as described in [1] reusing Fop instances is discouraged in 0.90 and
later. I'm currently working on a few changes that will address
performance considerations around reusable objects in FOP. The Fop
instance (and to a certain degree the FOUserAgent instance) are designed
to be one-use objects. The setup overhead for each rendering run is
minimal comparing that to the amount of new objects that have to be
(re)created for each rendering run (FO tree, layout engine, area tree,
renderers, PDF library). I also recently introduced a check in FOP Trunk
that will notify you if you try to reuse the Fop instance. So, please
don't reuse Fop instances.

Hmm, we have a test for that in our test suite which test exactly that
scenario: http://svn.apache.org/repos/asf/xmlgraphics/fop/trunk/test/layoutengine/standard-testcases/page-number-citation_basic.xml
Would you please put together a full FO file that produces this error
message? Thanks!
