undefined method errors after 0.2.18 update

[LeptonHeavy]

have script that combines latest version of a PDF from several folders in a hierarchy - combining them into a single PDF.

Under 0.2.17 it works as expected - under 0.2.18 I get an error when adding the second pdf to the new document.
error:

C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/combine_pdf-0.2.18/lib/combine_pdf/pdf_public.rb:303:in `insert': undefined method `update' for nil:NilClass (NoMethodError)
        from C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/combine_pdf-0.2.18/lib/combine_pdf/pdf_public.rb:275:in `<<'

        from C:/Users/User02/Documents/combinePDF/combine.rb:57:in `<main>'

ruby code

# file_list is an array of PDF files - something like:
# ["R:/Project DS/C/A1_3_151203_Construction.pdf", "R:/Project DS/B/A1_2_160410_Permit_Revisions.pdf","R:/Project DS/C/A1_3_160412_More_Permit_Revisions.pdf"]

pdf_merge = CombinePDF.new
file_list.each do |pdf_file|
  pdf_merge << CombinePDF.load(pdf_file)    
end

Hi @LeptonHeavy,

Thank you so much for pointing this out 👍 👍 👍

I uploaded a patched version to github. Could you check that this resolves the issue?

Thanks,
Bo.

I'm kind of new to github, so I'm still getting used to the functions of these comments.

I'm still having this same problem. Here's the error again:

C:/Ruby21/lib/ruby/gems/2.1.0/gems/combine_pdf-0.2.18/lib/combine_pdf/pdf_public.rb:303:in 'insert': undefined method 'update' for nil:NilClass (NoMethodError) from C:/Ruby21/lib/ruby/gems/2.1.0/gems/combine_pdf-0.2.18/lib/combine_pdf/pdf_public.rb:275:in '<<' from addinfo.rb:23:in '<main>'

My code is straight out of the combine_pdf.rb, and looks like this:
pdf = CombinePDF.new pdf << CombinePDF.load("file1.pdf") pdf << CombinePDF.load("file2.pdf") pdf.save "combined.pdf"

Since I'm new to github, I might simply not have the patch. I re-downloaded the zip, thinking that might solve the issue, but unfortunately it didn't. I'd love to use this gem for a project I'm working on for a class, though!

After downloading the zip, you need to copy (and overwrite) the pdf_public.rb file to the C:/Ruby21/lib/ruby/gems/2.1.0/gems/combine_pdf-0.2.18/lib/combine_pdf folder (the gem's folder).

After you overwrite the gem installation's file, you should have the patch.

The error might be resolved... of the error might move to a different line.

This week is finals at my collage, so I didn't get around to testing and releasing the patch. I'm not sure why the issue didn't come up with any of my pdf files when I was testing the 0.2.18 version.

[boazsegev]

I released a fixed version (v.0.2.20) - please check that this actually fixes the issue for you.

[EmberSher]

Alrighty! Thanks! I'll take a look right now

[EmberSher]

It worked! Thank you!

[boazsegev]

@EmberSher,

Thanks for letting me know and for reporting this issue and your experience.

@LeptonHeavy thanks again. Let me know if you have any issues, I'm closing this one for now.

[LeptonHeavy]

confirming that 0.2.20 works for me as well!
thanks for the speedy fix!

@LeptonHeavy , thanks for keeping me posted 👍
