| @DataModel
| private List<Kfz> bearbkfzList;
|
| @Begin(join=true)
| public String searchKfz(){
|
| currentPage=0;
| if ( ! bid.equals("") ){
| try{
| lid = Long.parseLong(bid);
| }catch(NumberFormatException ex){
| facesMessages.add("FNr ist keine Ziffer!");
| return "null";
| }
| }else{
| lid = 0L;
| }
| updateResults();
| if ((bearbkfzList == null) || (bearbkfzList.isEmpty()) ){
