爲什麼此方法不保存新選定的類別。我的代碼有問題嗎?爲什麼TextField中的setText不起作用?

catCon = new TextField(); 
rowEditing.addEditor(catConfig, catCon); 

這是用於設置catCon代碼:

TextButton save = new TextButton("Save"); 
save.addSelectHandler(new SelectEvent.SelectHandler() { 

      @Override 
      public void onSelect(SelectEvent event) { 

       selectedItems = new LinkedList<Short>(); 
       for (int i = 0; i < toCat.size(); i++) { 
        selectedItems.add(toCat.get(i).getIDCategory()); 
       } 
       Collections.sort(selectedItems); 
       newSelectedItems = selectedItems.toString().replace(",", "-").replace("[", "").replace("]", "").replace(" ", ""); 

       msg = new MessageBox("SELECTED ITEMSSSSSSSSS: " + selectedItems.size() + " " + newSelectedItems);; 
       msg.show(); 
       catCon.setText(newSelectedItems); 
       hide(); 
      } 
}); 

,這是其中的COMMITED改變保存:

rowEditing.getSaveButton().addSelectHandler(new SelectEvent.SelectHandler() { 

       @Override 
       public void onSelect(SelectEvent event) { 
        store.commitChanges(); 

        service.saveUserRights(store.get(index), new AsyncCallback<Boolean>() { 

         @Override 
         public void onFailure(Throwable caught) { 
          msg = new MessageBox("Error", caught.getMessage()); 
          msg.show(); 
         } 

         @Override 
         public void onSuccess(Boolean result) { 
          if (result) { 
           msg = new MessageBox("Information", "Changes saved."); 
           msg.show(); 
           service.getURListGrid(new AsyncCallback<List<UserRights>>() { 

            @Override 
            public void onFailure(Throwable caught) { 
             MessageBox msg = new MessageBox("Error", caught.getMessage()); 
             msg.show(); 
            } 

            @Override 
            public void onSuccess(List<UserRights> result) { 
             store = new ListStore<UserRights>(properties.idRight()); 
             store.addAll(result); 
             grid.reconfigure(store, cm); 
            } 
           }); 
          } else { 
           msg = new MessageBox("Error", "Failed to save changes."); 
           msg.show(); 
          } 
         } 
        }); 
       } 
      }); 

當我要設置catCon有將不會改變數據,但當我手動輸入類別時,將會有變化。有人能幫助我嗎?

當您啓用自動提交時會發生什麼? store.setAutoCommit(true) – udeleng 2015-02-25 00:54:23

@udeleng我會嘗試這一行代碼。謝謝 – 2015-02-25 01:07:52

@udeleng我很抱歉,但它不起作用。它不保存新選擇的類別 – 2015-02-25 01:13:23

爲了讓我保存當前的類別是讓店裏的指標和類別設置爲newSelectedItem

store.get(index).setCategories(newSelectedItems); 

我希望這將有助於誰具有相同的問題,因爲我的人。
