我想根据表单的内容更改 DataTable 的内容(将其视为搜索栏功能)。我曾经在 wicket 1.5.x 中这样做,但我似乎无法让它在 wicket 6.0.0-beta2 中工作。AjaxButton 的 onSubmit 方法中似乎没有进入。其他一切正常,每个组件都正确呈现,并且在页面加载时 dataTable 填充了正确的数据,但是当我单击按钮时,什么也没有发生。
任何帮助将不胜感激。这是我的代码的样子:
数据表:
public SubscriberPage(PageParameters parameters) { 
super(parameters); 
add(new SearchForm("searchForm")); 
List<IColumn<Subscriber, String>> columns = new ArrayList<IColumn<Subscriber, String>>(); 
columns.add(new PropertyColumn<Subscriber, String>(new Model<String>("Telephone Number"), 
                                                   "tn", 
                                                   "tn")); 
[...] 
columns.add(new PropertyColumn<Subscriber, String>(new Model<String>("Initialized MB"), 
                                                   "initializedMB")); 
table = new AjaxFallbackDefaultDataTable<Subscriber, String>("table", 
                                                             columns, 
                                                             subscriberDataProvider, 
                                                             40); 
table.setOutputMarkupId(true); 
add(table); 
} 
这是带有 AjaxButton 的表单:
private class SearchForm extends Form<String> { 
private static final long serialVersionUID = 1L; 
private String tnModel; 
private Label tnLabel = new Label("tnLabel", "Telephone Number :"); 
private TextField<String> tn; 
public SearchForm(String id) { 
  super(id); 
  tn = new TextField<String>("tnTextField", new PropertyModel<String>(this, "tnModel")); 
  tn.setOutputMarkupId(true); 
  add(tnLabel); 
  add(tn); 
  AjaxButton lSearchButton = new AjaxButton("searchButton") { 
    private static final long serialVersionUID = 1L; 
    @Override 
    protected void onSubmit(AjaxRequestTarget target, Form<?> form) { 
      SubscriberFilter filter = new SubscriberFilter(); 
      target.add(table); 
      if (!(tn.getValue() == null) && !tn.getValue().isEmpty()) { 
        filter.setTn(tn.getValue()); 
      } 
      // giving the new filter to the dataProvider 
      subscriberDataProvider.setFilterState(filter); 
    } 
    @Override 
    protected void onError(AjaxRequestTarget target, Form<?> form) { 
      // TODO Implement onError(..) 
      throw new UnsupportedOperationException("Not yet implemented."); 
    } 
  }; 
  lSearchButton.setOutputMarkupId(true); 
  this.setDefaultButton(lSearchButton); 
  add(lSearchButton); 
} 
}
