error when try to convert docx which has tables to pdf

[bzha005]

Hi Jason,
When I try to convert your /sample-docs/databinding/invoice.docx to pdf using docx4j 2.5.0, I got the following error, any ideas?

Thanks for reporting this. This is caused by an sdt (content control) in the place of a row.

It is fixed in http://dev.plutext.org/trac/docx4j/changeset/1188

If you drop in http://dev.plutext.org/docx4j/docx4j-ni ... 100824.jar in place of the 2.5.0 jar, you should find it works.

Hi Jason,
Thanks for your reply. it works. However, there are still following issues.
I used invoice.docx as template to generate my invoice_bound.docx by replacing the custom xml file programmely, I got the expect docx file with 3 rows but after I coverted invoice_bound.docx to pdf I got one row pdf and table border is gone. I have zipped and attached the files for your reference.

[jason]

1. http://dev.plutext.org/trac/docx4j/changeset/1189 handles multiple tr in the sdt.

I looked at your docx and the resulting pdf.

2. Looks like an enhancement is required before docx4j supports your shaded row.

3. Also, I notice that the structure:

Code: Select all

       <w:p w:rsidRDefault="002E7764" w:rsidP="00926DAD" w:rsidR="00926DAD">
          <w:r>
            <w:t>Joe Bloggs</w:t>
          </w:r>
          <w:proofErr w:type="spellStart"/>
          <w:r>
            <w:t>Joe Bloggs</w:t>
          </w:r>
          <w:proofErr w:type="spellEnd"/>
        </w:p>


is resulting in Joe Bloggs appearing twice in the pdf. I will look into fixing this proofErr in the next day or so. In the meantime, the workaround would be to ensure you document doesn't contain any of these.

Did you see the link to the docx4j user survey? Please take the survey, if you haven't already done so. Thanks!

Hi Jason,

I found some more related errors. there are 2 small word files in the attached zip file. I opened the simple-test.doc in word 2007 and saved it as simple-test.docx, then tried to convert simple-test.docx to pdf using docx4j and I got the following error.

tried to convert simple-test.docx to pdf using docx4j and I got the following error.

Works for me (ie no FOP error) using current svn tip.

Note that your document contains fields, in particular to set and reference variables. docx4j PDF output does not honour fields, except for page number fields.

Support for those could be added, or you could consider using the data binding stuff instead.

is resulting in Joe Bloggs appearing twice in the pdf. I will look into fixing this proofErr in the next day or so. In the meantime, the workaround would be to ensure you document doesn't contain any of these.

Looking at this more closely, things seem to be ok as they are.

The original Word document had:

Code: Select all

      <w:p w:rsidRDefault="002E7764" w:rsidP="00926DAD" w:rsidR="00926DAD">
          <w:r>
            <w:t>Joe Bloggs</w:t>
          </w:r>
          <w:proofErr w:type="spellStart"/>
          <w:r>
            <w:t>Joe Bloggs</w:t>
          </w:r>
          <w:proofErr w:type="spellEnd"/>
        </w:p>


When opened in Word, it showed only one "Joe Bloggs". This isn't because the second is surrounded by w:proofErr, but rather, because the binding is performed, replacing the paragraph contents (with the bound XML, which in this case was also Joe Bloggs).

So the docx4j pdf output should produce the same result, providing the binding is resolved first.

Hi, I add my post to this thread because I met the same issues with the current versions 2.8.1 and 2.9.0-SNAPSHOT and the proposed work arounds did not help (invalid link). Maybe you have a solution to my problem: I tried to convert bypacked docx file to pdf. The docx file was constructed from a template by a tool named OfficeAtWork. The thrown exception is:

Is there a solution for this?

Thank you!

Thanks for reporting this. The problem was a bookmarkStart between table rows.

https://github.com/plutext/docx4j/commi ... 0f8a16301f fixes this issue.

I notice your document uses a variety of fields liberally. I'm afraid the PDF output doesn't handle these at present. I think one of the other docx4j developers is planning to do some work on this, so this might change relatively soon, but no promises.

Hi Jason,

thank you for the quick response!
