Subject RE: Create damaged PDF file
Date Mon, 25 Jan 2010 17:32:41 GMT
Maybe I should make it clear again: I get the same FOP error message from exact same set of
data(XML) and same template and it only happens once in a while. I am not sure the error message
was generated from different tables or same table. Worst thing is that I cannot re-create
this in my unit test and local server environment.

Hi Zemin, 

first you need to get your hands on a fo file which produces the error. From there you can
work your ways back into xml to find where the error is produced. The error message clearly
states you have a table row without table cells. I don't think you can avoid going through
your file and find this row...

Betreff: RE: Create damaged PDF file

I am using XML+XSLT combination as you indicated, but the error message is NOT consistent,
it may disappear on next run, so I don't know how to debug my template to be clean since it
is clean most of the time.

Thanks for pointing out to me the configuration option, I was going to test, but after reading
document from your URL, I found it won't help in this case because the default value for "strict-configuration"
option is "false" already.

as the error message said, you have an empty fo:table-row in the resulting XSL-FO file.
I guess you use a XML + XSLT couple to get such file, therefore you should debug your XSLT
to produce a clean, valid XSL-FO code.

An alternative is to configure FOP to be more "laxist". See "strict-configuration" option
in FOP configuration [1].
