     public void setAddressLineIndex(int theAddressLineIndex) {
          myAddressLineIndex = theAddressLineIndex;
     public void actionAddAddressLine() {
               if (theprogram.getProgram() == null || theprogram.getProgram().length == 0) {
                    theprogram.setProgram(new String[]{programInstance});
               }else {
                    List lines = new LinkedList(Arrays.asList(theprogram.getProgram()));
                    if (lines.contains(programInstance)) {
                    }else if (myAddressLineIndex > -1) {
                         lines.remove(myAddressLineIndex);
                         lines.add(myAddressLineIndex, programInstance);
                    }else {
                         lines.add(programInstance);
                    theprogram.setProgram((String[])lines.toArray(new String[lines.size()]));
               programInstance = "";
