It was fixed here.

Thanks Pawel.

I just installed xhtml2pdf using pip. This installs the 0.0.4 version. Therefore I stumbled over the same issue.

Whereas I will use now the latest source code from github to overcome this issue, I want to ask whether there is already a release date, including this fix, planned for the next version?

Not really, but if I can quite easily push a new release out if that
would be a good thing (tm).
I don't have an enormous quantity of spare time these days, so it
would really help if somebody would step up and helped me with the
maintenance - I would really appreciate it.

- Chris

hi chris,

for me it looks like a lot of xhtml2pdf beginners will stumble over this bug. I actually just used the example from the readme in your django-xhtml2pdf lib, combined with the test_pdf provided here: https://github.com/chrisglass/django-xhtml2pdf/blob/master/django_xhtml2pdf/templates/test_pdf.html

Therefore I think it would be good to have a release date soon, including at least this fix.

I have quite a bit python / django experience, I used reportlab for my last project, and was looking now for a wrapper that helps me with the basic stuff, as I was not really happy dealing with the low-level api of reportlab. See also my SOF question related to this topic: http://stackoverflow.com/questions/14609182/reportlab-wrapper

I'm not a full-time web-developer, and as for the most uf us, also do not have a lot of spare time. Anyhow, I will try out the xhtml2pdf and django-xhtml2pdf as I really like the concept. Anyhow, looking at the complexity of the project, the time I would be able to devote, and my experience with your lib, I'm a bit scared that I will be much of use. I will also give https://github.com/matthiask/pdfdocument a try to see whether this project might fit my needs.

Thumbs up for the good work you provided.

Yeah - would love to see a quick fix get pushed to easy_install. If it's indeed a one line change, shouldn't take too long...
