After upgrading from 22.1.42 to the 22.1.67 the following pdf will generate an exception now. https://www.fmcsa.dot.gov/sites/fmcsa.dot.gov/files/2022-03/Medical%20Examiner%27s%20Certificate%20Form%20MCSA-5876.pdfQuote:System.Exception: Target can not be null.

at EO.Pdf.PdfField.blwy()
at EO.Internal.fjph.blwy()
at EO.Pdf.PdfDocument.nxik()
at EO.Pdf.PdfDocument.Save(Stream stream) It's specifically the three PdfComboBoxField State Fields that cause the error. I believe it might be related to them having Items with only Labels and null Values. In the previous version there was also a problem when viewing the filled document in Chrome. The selected item is not visible until it the input receives focus but it displays fine in Adobe Reader. Quote: [TestMethod]
public void WorksBefore1()
{
PdfDocument doc = new PdfDocument(PdfFileName);
var field = doc.Fields["cmvState"] as PdfComboBoxField;
field.SelectedIndex = 1;
field.Modified();
doc.Save("../../../output1.pdf");
}
[TestMethod]
public void WorksBefore2()
{
PdfDocument doc = new PdfDocument(PdfFileName);
var field = doc.Fields["cmvState"] as PdfComboBoxField;
field.Value = "TX";
field.Modified();
doc.Save("../../../output2.pdf");
}

On the second part about the forms not showing the value until they receive focus this might be relevant. It's a separate project pdfium but it's also based on chrome so there might be some similar base source. https://stackoverflow.com/questions/66227256/when-filling-a-pdf-document-with-pdfsharp-the-filled-form-doesnt-show-the-valu[quote] if (acroForms.Elements.ContainsKey("/NeedAppearances")) acroForms.Elements["/NeedAppearances"] = new PdfBoolean(true); else acroForms.Elements.Add("/NeedAppearances", new PdfBoolean(true)); [quote]
