Help! Doesn't save field updates.

[bmorgy]

PdfReader works fine, reads a simple PDF with fields and correctly identifies every field. I update a field value (see below), and create the filled-out.pdf file. The file is created perfectly but doesn't contain my field value. What's am I doing wrong?

I'm using the example code as follows:

`from pypdf import PdfReader, PdfWriter

reader = PdfReader("form.pdf")
writer = PdfWriter()

page = reader.pages[0]
fields = reader.get_form_text_fields()

writer.add_page(page)

writer.update_page_form_field_values(
writer.pages[0], {"employee_name":"John Smith"} )

with open("filled-out.pdf", "wb") as output_stream:
writer.write(output_stream)`

add_page() only copies the page not the rest of the structure; you have to use append()
