Description

This code

PDField newField = tplDoc.getDocumentCatalog().getAcroForm().getField("01.20.Entry1");
PDCheckbox newCheckBoxField = (PDCheckbox) newField;
newCheckBoxField.check();

brings this exception:

Exception in thread "main" java.lang.UnsupportedOperationException: not implemented
	at org.apache.pdfbox.pdmodel.interactive.form.PDButton.constructAppearances(PDButton.java:225)
	at org.apache.pdfbox.pdmodel.interactive.form.PDTerminalField.applyChange(PDTerminalField.java:220)
	at org.apache.pdfbox.pdmodel.interactive.form.PDCheckbox.setValue(PDCheckbox.java:128)
	at org.apache.pdfbox.pdmodel.interactive.form.PDCheckbox.check(PDCheckbox.java:71)

what did work is this:

newCheckBoxField.getCOSObject().setItem(COSName.V, vValue);
newCheckBoxField.getCOSObject().setItem(COSName.AS, asValue);
