----------------------------------------
[~scoldwell] could you test with 2.0.3 or trunk if the changes are fixing your
issue and are inline with your expected results. BTW. the different radio
buttons in the form would better be grouped e.g.OPTB.1-OPTB.5 as this would
ensure that used interactively only one option can be selected instead of
multiple.
> PDButton.getOnValues seems to be using the wrong source for getting the
> allowed values

> 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}
