Export to PDF

[darkwolf-zz]

Hi!, when I try to export reports to pdf I can't do it.
I'm not sure if I need any gem to do it or it's a bug.
And I noticed when I do the search, the PDF icon is not displayed as in the flash tutorial.

I installed CentOS v5.4, mysql 5.0.77-4.el5_4.1, ruby 1.8.5

Thanks for all.

@Darkwolf this is a strange error. What version of prawn do you have installed?

gem list

Hi mephux, thanks for answer.
I have installed : prawn (0.7.1).
In other pc, I tried to install rails v 2.3.2 (gem install rails -v=2.3.2 ), and changed it in environment.rb (RAILS_GEM_VERSION = ), but it's the same error.

I got same error... and i think the error its about the prawn version we are using.

http://wiki.github.com/sandal/prawn/changelog
This: "removed header() and footer() methods, use Prawn::Document#repeat
instead."

[andreshans]

workaround:
gem install --version=0.6.2 prawn prawn-core (it will take a long time)
then... gem list and uninstall the older version with:
gem uninstall --version=x.x.x praw
gem uninstall --version=x.x.x praw-core
and when you get in the browser "File not found xxxxx.pdf" just hit refesh.
and remember: it just a workaround
