Aspose.PDF Submit button generates "Expected a name object" error

I am in process of converting Aspose.Pdf.Kit to Aspose.Pdf.Facade (Latest released on 4/1/2014).

I am adding “submit” buttons to every page in a PDF file. When implemented in Pdf.Kit, it worked fine.

But when I changed it to Pdf.Facade, I started getting “Expected a name object” error as shown in the attachment.

I searched for an answer on the forum but the closed thing I got was this
Adobe Reader Error: Expected a name object}", queryArg.GetQueryStringText());
for (int i = 0; i < pageCount; i++)
string label = “Submit”;
if (shouldLockForm) label = “Submitted”;

fe.SubmitFlag = SubmitFormFlag.Fdf;
fe.AddSubmitBtn(string.Format("SUBMITFORM{0}", i + 1), i + 1, label, submissionUrl,
500, 765, 600, 790);


I have cleared all radio button values before saving and the error doesn’t occur. So what I think is this has something to do with radio buttons.

I tried to “touch” a random radiobutton but I am still getting “Expected a name object”

Hi Sung,

Thanks for contacting support.

I have tested the scenario using Aspose.Pdf for .NET 9.1.0 where I have used one of my sample PDF files and I am unable to notice any problem. When I press the submit button, no error message appears (except a message stating that an error occurred during submit process). Can you please share the source PDF form which you are using so that we can again try replicating the issue at our end. We are sorry for this inconvenience.


FormEditor fe = new


string submissionUrl = "http://localhost/";

for (int i = 0; i < new PdfFileInfo("c:/pdftest/PTS_Form_2014_v1.3_clear.pdf").NumberOfPages; i++)


string label = "Submit";

//if (shouldLockForm) label = "Submitted";

fe.SubmitFlag = SubmitFormFlag.Fdf;

fe.AddSubmitBtn(string.Format("SUBMITFORM_{0}", i + 1), i + 1, label, submissionUrl,

500, 765, 600, 790);



Hi Nayyer.

I have added the sample application & PDF form that generates “Expected a name object” error when you press the submit button on the top right. ( I didn’t include the license file in the zip. Let me know where I should email the license file if you need it )

When you clear 2 radiobuttons by clicking on “clear” buttons, you can now submit without error.
