PDAppearanceCharacteristicsDictionary only defines settings for the creation of the appearance stream but doesn't create it. What you need is the content of the appearance stream. Unfortunately I'm in the middle of a project so can't help much further at the moment. What you could do if the form is opened in Adobe Acrobat or Reader is to set the NeedAppearances flag for the AcroForm. This will trigger Adobe Reader/Acrobat to build the appearance once the form is opened. This shall only be treated as a workaround as this will not work in most other readers or when rendering the form throufgh PDFBox or others. I'll try to get something prepared tomorrow morning for you if you havn't found a solution by then.
