updated:

here binding tableview , data

private void initclstable() {                system.out.println("in inintclstable");         bindings.bindcontentbidirectional(tblviewer.getcolumns(), getviewmodel().getcolumnlist());         bindings.bindcontentbidirectional(tblviewer.getitems(), getviewmodel().getdatalist());     } 

here selection taken place: (when user changes selection)

private void subscribechoosentabledataconfig() {         this.columnslist.clear();         this.datalist.clear();         system.out.println("subscribechoosentabledataconfig");               if (choosentabledataconfig.get() != null && choosentabledataconfig.getvalue().gettablename() != null                 && choosentabledataconfig.getvalue().gettablenumber() != 0) {             clsmanager.tell(new clsmanager.clstabledatarequest(eventhandler, choosentabledataconfig.getvalue()                     .gettablename(), choosentabledataconfig.getvalue().gettablenumber()), actorref.nosender());         }     } 

by removing these 2 lines have wanted.

this.columnslist.clear(); this.datalist.clear();
