read, then immediately write, does not preserve info #181

I have a pdf file with a fillable form. I fill out the form and save the file. I can view the file with any number of pdf viewer/editors and the fields I added to the form are there. Yet when I simply use pdfrw.PdfReader to read it (the filled out pdf), then immediately invoke pdfrw.PdfWriter to write it back out, all the fields I previously filled out are empty in the output file. Why would this happen?

Were you able to figure out a solution?

No.

I am experiencing this problem right now. I'm filling out forms across multiple PDFs, then later I PdfReader() them in to assemble them into one giant PDF and the forms have all blanked out.

I think this might be because writing the .pages doesn't carry over the Root of the document that's being written. I'm not sure how one would go about copying over the elements (like AcroForm)

I discovered this on another comment, thanks @starlabs007 : https://stackoverflow.com/questions/57008782/pypdf2-pdffilemerger-loosing-pdf-module-in-merged-file

This works for me.
