That is true, but if generated pdf is an end product, that may be adequate.
The point I am trying to make is that if the pdf was created with Designer,
setListOption causes a nullpointer if you use the field name instead of the
field key, which is somewhat confusing if you are also using setField. For
posterity:
AcroFields fields=stamper.getAcroFields();
boolean bSuccess=fields.setField("state", "MI"); //Works for
Designer-generated PDF's only
bSuccess=fields.setListOption("state", new String[]{"IN","MI","OH"},new
String[]{"Indiana","Ohio","Michigan"}); //Causes error for Designer-produced
PDF's, just fails for others (becuase state is not the Item key)
bSuccess=fields.setListOption("app[0].page1Form[0].state[0]", new
String[]{"IN","MI","OH"},new String[]{"Indiana","Michigan","Ohio"}); //works
for all, values will show in Reader but not Designer
Thank you,
Dave

It looks like it works but it doesn't. It changes the acroform but not
the xfa and if you return to Designer the changes will be gone.
