Thanks, it is working. Now I can see the button. I need to understand this. I am a developer (java, c, .net, etc.) but I do not know PDF format and I am new to PDFBox (used iText long ago).
The Javadocs states: public void setNeedAppearances(Boolean <http://download.oracle.com/javase/1.6.0/docs/api/java/lang/Boolean.html?is-external=true> value) Set the NeedAppearances value. *If this is false, *PDFBox will create appearances for all field widget. The javadoc does not say what happens if you set to TRUE. You set to TRUE and the widget is visible, then I don't understand what "appearances" is (and I think I don't understand differences between appearances and widgets). Also, the text field was already visibel (with border and background colors). Thanks again.
