Getting correct widget ref to be removed

[kyle-leitham-aix]

What?

Gets correct widget ref from the document to remove the corresponding annotation ref from the page

Why?

Trying to fix this issue: #1267

How?

Gets the ref using doc.context.getObjectRef instead of findWidgetAppearanceRef (which seems to get the wrong ref?)

Testing?

Ran the unit tests

New Dependencies?

N/A

Screenshots

N/A

Suggested Reading?

No

Anything Else?

I'm new to this repo and PDF specifications, so I'm not sure this is the correct fix. Hoping it is!

@kyle-leitham-aix do you know if there is any progress on this? I'm also running into this issue and marking the fields read-only isn't really an option since they're still editable. Any further info?

@mel-habip It seems like this repo has been abandoned, unfortunately. As a workaround, I had to programmatically remove all of the page annotations before flattening.

Could you provide an example of how to do this? We tried this but didn't quite work out for us.

@mpalmahsf So, if you have the pdf document instance, it would be something like:

pdfDocument.getPages().forEach((page) => {
      const annotations = page.node.Annots()
      const size = annotations?.size()
      if (size) {
        for (let i = 0; i < size; i++) {
          annotations.remove(annotations.get(i))
        }
      }
    })

There is an issue with this approach.
After this fix adobe no more throw any error but all fields & texts are missing from the pdf(Just an empty PDF page).

          annotations.remove(annotations.get(i))
        }
      }
    })

I tried this approach and worked but I applied that AFTER flattening the form. In that way the fields and texts appear well.
