--------------------------------------
Summary: PDButton.getOnValues seems to be using the wrong source
for getting the allowed values
Key: PDFBOX-3391
URL: https://issues.apache.org/jira/browse/PDFBOX-3391
Project: PDFBox
Issue Type: Bug
Components: AcroForm
Affects Versions: 2.0.1
Reporter: Scott Coldwell
We are in the process of migrating from itext to pdfbox and noticed that an
exception was being thrown when trying to set a radio button with
PDField.setValue(). The values returned from PDButton.getOnValues() which is
used by PDButton.checkValue() called from PDButton.setValue() are only
returning 0,1 instead of what we had been using with itext. After
investigating itext's source code and playing around with pdfbox I was able to
get to what I believe are the appropriate allowed values by using the following
code.
{code}
if (field instanceof PDButton)
{
final COSBase item = field.getCOSObject().getItem(COSName.OPT);
if (item != null && item instanceof COSArray)
{
final COSArray optArray = (COSArray)item;
for (int i = 0 ; i < optArray.size() ; i++)
{
// Each item in this array is an allowed value
// optArray.getString(i);
}
}
}
{code}
