 In the saved PDF, there is no text at the ComboBox's location, but using PDFDebugger the
annotation and Opts are still there.  Just not visible...?  "V" is the correct value as set.

But they have exactly the same text, and I'm able to search through them for equal strings
in order to determine the index.

which version of PDFBox are you using? How do you set the value? Would you have a sample PDF
to be able to give you some specific code (please upload to a shared location)?
