I am getting cryptic error messages trying to render a pdf file using xml:
Exception at /url/
('Unable to generate PDF.', b'Exception\norg.apache.fop.apps.FOPException: org.apache.fop.fo.ValidationException:
The column-number or number of cells in the row overflows the number of fo:table-columns specified for the table.
(See position 31:15)\njavax.xml.transform.TransformerException: org.apache.fop.fo.ValidationException:
The column-number or number of cells in the row overflows the number of fo:table-columns specified for the table. (See position 31:15)\n\n')
The only thing I'm changing is the <column name="Record date Ex-dividend date Payable Date" size="4.2cm"></column>. This matches the format the pdf was made with in Perl, and removing that one column line fixes the pdf and it works.
{% block pages %}
<schedule_page>
<columns>
<column name="Record date Ex-dividend date Payable Date" size="4.2cm"></column>
{% for date_set in dist_dates %}
<column name="{{ date_set.record_date|date:'j-M' }} {{ date_set.ex_date|date:'j-M' }} {{ date_set.pay_date|date:'j-M' }}" size="1.675cm" margin="0.1cm"></column>
{% endfor %}
</columns>
<data>
{% regroup portfolios by group as portfolio_groups %}
{% for portfolio_group in portfolio_groups %}
<group name="{{ portfolio_group.grouper }}">
{% for portfolio in portfolio_group.list %}
<fund name="{{ portfolio.name }}">
{% for dist in portfolio.distributions %}
<cell value="{{ dist.value }}" {% if dist.value %}margin="0.1cm"{% endif %} ></cell>
{% endfor %}
</fund>
{% endfor %}
</group>
{% endfor %}
</data>
</schedule_page>
{% endblock %}
The fo file that precedes the pdf looks like:

Why is adding this single line blowing up my pdf download? Thank you
It looks like that, with FOP, you need one fo:table-column for each column in the table or you need none.
The XSL 1.1 Recommendation doesn't require that, AFAICT, but it also doesn't say what happens for a mismatch in column counts.
Since you say you remove one line and produce no fo:table-column, and since you are seemingly also generating fo:table-column based on dist_dates and generating fo:table-cell based on portfolio information, it seems like your logic to generate fo:table-column isn't quite right. Unless you need the width or other properties set on the fo:table-column, there's no harm done if you omit them.
