Hi Eric, you posted this in the UWP forums (Universal Windows Platform). Can you please confirm exactly what type of application this code is being run in? Did you intend to select WinForms, WPF or WinUI3?

[Eric]

yes it is a winforms application, in C#

Hi Eric,

Thank you for sharing the feedback and the document with us.

I tried to reproduce the described behavior with the provided document and it seems it works as expected (without any exceptions) with the current version of the PdfProcessing binaries. 

It could be an issue that is already fixed. Could I ask you to update the version with the latest and test if this behavior still exists?

I am attaching the sample project I created in order to test this behavior. Please, feel free to modify it in a way closer to your scenario.

Hello,

I still have a problem on some pdf that I can't read with this code :

string InputFileWithInteractiveForms7 = RootDirectory + "SampleData\\FICHE_DE_CONTROLE.pdf";
            PdfFormatProvider provider = new PdfFormatProvider();
            RadFixedDocument document = provider.Import(File.ReadAllBytes(InputFileWithInteractiveForms7));

I have the following error message :

it works with some pdf but others don't. I can't find why.

it's the same reaction with your test solution. I use the dll version 2021...

I attach my file. Thank you for your help.

Hi Eric,

Thank you for sharing the document with us. This helps me to reproduce the described behavior.

It seems it is caused by an issue related to the normal appearance of the Widget annotations. I logged an item on your behalf to fix it: PdfProcessing: ArgumentNullException is thrown when importing a document containing Widget annotation with normal appearance dictionary set to null.

Martin,

it would seem that the problem is on the checkboxes.

we have made some test pdfs (attached).

I don't know if it can help you?

[Martin]

Thank you for the additional sample documents.

Indeed the problem is with the checkboxes.

We are currently investigating this issue.
