Description

Using SVN trunk revision 1291094 (2012-02-18)
Getting the following stack trace when trying to call PDField.setValue() on a AcroForm field in the attached document;

java.lang.NullPointerException
at org.apache.pdfbox.pdmodel.interactive.form.PDAppearance.calculateFontSize(PDAppearance.java:551)
at org.apache.pdfbox.pdmodel.interactive.form.PDAppearance.insertGeneratedAppearance(PDAppearance.java:371)
at org.apache.pdfbox.pdmodel.interactive.form.PDAppearance.setAppearanceValue(PDAppearance.java:281)
at org.apache.pdfbox.pdmodel.interactive.form.PDVariableText.setValue(PDVariableText.java:131)

Reason seems to be that PDApperance.getFontAndUpdateResources() returns null, in turn because the font dictionary for the DA of the field ("/Cour 11 Tf 0 g") is not present in the document.
