Thank you John. I really don't care very much about these OnValue and OffValue, except that there was a piece of bizzarre behavior that I used them to work around.
On some pdf viewers (like Preview on the mac), if you did not SPECIFICALLY set the value of the check box to the on vlaue string, the checkbox would appear unchecked even though in pdf box introspection would show it as being checked. So I had a hack workaround where, in addition to checking the checkbox I also set the value to the OnValue. The universe of pdf viewers is vast and disturbingly inconsistent and buggy. Thank you for your explanation. I found several places in the pdfbox 2.0 Javadoc that seem wrong. So it needs attention. thank you.
