This is intented. Setting {{needAppearances(false)}} will skip generating the
visual content of the field (the appearance).

Hhmmm, the JavaDocs of {{PDAcroForm.setNeedAppearances(Boolean)}} claim that
for {{false}} PDFBox *does generate the visual contents*:
{code:java}
/**
* Set the NeedAppearances value. If this is false, PDFBox will create
appearances for all field
* widget.
*
* @param value the value for NeedAppearances
*/
public void setNeedAppearances(Boolean value)
{
dictionary.setBoolean(COSName.NEED_APPEARANCES, value);
}
{code}
And this makes sense, setting *NeedAppearances* to *false* in the *AcroForm*
dictionary effectively tells the next PDF processor that all the widget
appearances are there and up-to-date...
