java - right click popup menu is not working properly (in jtable) -

-

its working first time after deleting line shows blank on popup menu in right click. think because of refresh method couldn't solve it.

private void refresh() {     list<string> head = new arraylist<>();     head.add("id");     head.add("П/Н");      enlargealistablemodel model = new enlargealistablemodel(dbsql.listalis(), head) {     // *****************     };     tblenlarge.setmodel(model);      tblenlarge.addmouselistener(new mouseadapter() {         @override         public void mousereleased(mouseevent e) {             if (e.ispopuptrigger()) {                 popup.removeall();                 jmenuitem delete = new jmenuitem("delete");                 delete.addactionlistener(new actionlistener() {                     @override                     public void actionperformed(actionevent e) {                         if (tblenlarge.getselectedrow() == -1) {                         } else {                             deleteenlargealis da = new deleteenlargealis(null, true, integer.parseint(tblenlarge.getvalueat(tblenlarge.getselectedrow(), 0).tostring()));                             da.setvisible(true);                             if (da.isok()) {                                 ok = true;                                 refresh();                             }                         }                     }                 });                 //  ********************                 popup.add(delete);                 popup.show(e.getcomponent(), e.getx(), e.gety());             }         }     });
