This is not supported yet, but as your project is stuck without it,
I wrote this method that will be added to the AcroFields class in
the next release:
public String[] getListSelection(String name) {
String[] ret;
String s = getField(name);
if (s == null) {
ret = new String[]{};
}
else {
ret = new String[]{ s };
}
Item item = (Item)fields.get(name);
if (item == null)
return ret;
PdfArray values =
(PdfArray)PdfReader.getPdfObject(((PdfDictionary)item.merged.get(0)).get(PdfName.I));
if (values == null)
return ret;
ret = new String[values.size()];
String[] options = getListOptionExport(name);
PdfNumber n;
int idx = 0;
for (Iterator i = values.listIterator(); i.hasNext(); ) {
n = (PdfNumber)i.next();
ret[idx++] = options[n.intValue()];
}
return ret;
}
If this method 'unstuck' your project, there's a PayPal button
