Hi,
I went ahead and fixed this problem and it should be in the next release (5.4.1, released in the next week). Even though the JavaDocs of getAppearance(fieldName) did not mention it applied to a Combobox, it should process it correctly. AcroFields.getAppearance(fieldName) now returns the display values (not the export values). Do note that there are other methods to retrieve the display/export values of a combobox: AcroFields.getListOptionDisplay(fieldName); AcroFields.getListOptionExport(fieldName); These return the values in an ordered array. These two methods are described in the documentation (iText in Action Second Edition, p255). Kind regards, Michaël.
