Thanks for the excellent PDF library. For my use case I need to flatten a subset of the AcroForm fields. I was attempting to use the PDAcroForm.flatten call, passing in my field list. However, after the method is called, all the fields are gone.
The method itself appears to remove all PDFAnnotationWidgets from each page and at the end clears the acroform's field set.
Is the javadoc description (This will flatten the specified form fields.) just misleading? Could a flatten call for a subset of fields be added?
