Travis Schneeberger updated PDFBOX-3752:
----------------------------------------
Description:
PDVariableText text color changes to be the same as the background color after
flattening. This effectively makes the text hidden and appear to be lost.
This includes field types such as ListBox and TextField. I don't believe I
have tested a combo box.
For example:
{code}
try(PDDocument pdfDocument = PDDocument.load(new
File("/Users/travis/Desktop/fdpAttachment2.pdf"))) {
final PDDocumentCatalog docCatalog =
pdfDocument.getDocumentCatalog();
final PDAcroForm acroForm = docCatalog.getAcroForm();
final PDField textField = acroForm.getField("Subaward Number");
textField.setValue("12345");
final PDField listBoxField = acroForm.getField("Contact for
carryforward");
listBoxField.setValue("Administrative Contact");
//when flattening with refreshAppearances, a NPE will occur if each
widget doesn't have a
//PDAppearanceDictionary instance with a normal PDAppearanceEntry
instance set PDFBOX-3751
pdfDocument.getDocumentCatalog().getAcroForm().getFields()
.stream()
.flatMap(f -> f.getWidgets().stream())
.filter(w -> w.getAppearance() == null)
.forEach(w -> {
final PDAppearanceDictionary appearance = new
PDAppearanceDictionary(new COSDictionary());
appearance.setNormalAppearance(new
PDAppearanceEntry(new COSDictionary()));
w.setAppearance(appearance);
});
pdfDocument.getDocumentCatalog().getAcroForm().flatten(pdfDocument.getDocumentCatalog().getAcroForm().getFields(),
true);
pdfDocument.save("/Users/travis/Desktop/fdpAttachment2-example-flattened.pdf");
}
{code}
Notice in the attached fdpAttachment2-example-flattened.pdf, the fields are
correctly set but the text is not visible.
If I execute the same code but do not flatten, the text is visible for certain
field types in certain pdf viewers. See attached
fdpAttachment2-example-not-flattened.pdf
In Adobe Acrobat Reader DC build 15.23.20056.213124 the "Subaward Number" field
shows up but only when clicking on the field. When using the Preview app in
MacOS Sierra, it is visible. In both apps the "Contact for carryforward" list
box shows the text "Administrative Contact"
