Hi, I''ve got a Rails app working that includes two two classes, etc.: Expense & Vendor.

Hi, while generating the PDF file , i am getting following error.. please help for me.

So, here''s the offending line. Note that I''m using edge rails. form_tag verifications_path(@user), :method => :post do verifications_path(@user) returns a string like "/users/3/ verifications".

I have a strange problem with setting request.format = :mobile I can reproduce this problem on a completely fresh Rails 3.0.7 app with no special gems.
