Empty sequence error from fo:table-column when editing FO with 22.0

When I create FO with tables that start with fo:table-column in 22.0 and open it in Oxygen Developer, I get the message:
An empty sequence is not allowed as the first argument of ahf:parser-runner()
I don't get this message with the same FO in 21.1. If I click on the message, it opens up C:\Program Files\Oxygen XML Developer 22\frameworks\focheck\schematron\focheck.sch
I am able to replicate this when I open C:\Program Files\Oxygen XML Developer 22\samples\fo\Miscellaneous\table.fo
Commenting out the fo-table-column elements gets rid of the error (also makes my tables format incorrectly, but . . .).

Hi,
In Oxygen 22.0 we updated the XSL-FO validation engine and possibly this added the problem you report.
Can you post a small sample XSL-FO file exhibiting the problem? I cannot reproduce this on my side with the XSL-FO sample I created:
Code: Select all
.....
<fo:table>
<fo:table-column />
<fo:table-body></fo:table-body>
</fo:table>
....
Regards,
Radu

Hi Radu, it fails for me with both of these:
My test case:
Code: Select all
<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>

<fo:region-body margin-top="12mm" margin-bottom="9mm"/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="MainDocument" initial-page-number="1"
force-page-count="no-force">
<fo:flow flow-name="xsl-region-body">

tables.fo from your samples:
Code: Select all

Hi,
Thanks for the samples, we will have a fix for this in the next Oxygen 22.0 minor bug fix release, in a couple of weeks.
We reported the fix on the "focheck" project and it was also fixed there:

Thanks so much, Radu. I have included the changes and I no longer get the error.

Hi,
As an update, the recently released Oxygen version 22.1 has an update fo check framework which no longer has the original problem.

Radu
