Question

在Wicket Panel中，我实现了一个名为showAttentiePopup（AjaxRequestTarget）的方法，该方法显示了一个ModalWindow弹出屏幕。当我从同一个Panel调用它时，此方法正常工作。但是当我尝试从另一个Panel调用该方法时，它崩溃并出现以下错误：

有人知道问题可能是什么？

方法showAttentiePopup：

   public void showAttentiePopup(AjaxRequestTarget target) {
         Component content = new EditAttentiePanel(createAttentie.getContentId(), new Attentie(), EditFunctie.AANMAKEN) {

                /** */
                private static final long serialVersionUID = 1L;

                @Override
                protected void annuleren(AjaxRequestTarget target) {

                       FKSModalWindow.closeCurrentWindow(target);
                }

                @Override
                protected void opslaan(AjaxRequestTarget target, Attentie attentie) {
                       //Inhoud even weggelaten
                }

         };

         createAttentie.setOutputMarkupId(true);
         createAttentie.setInitialWidth(900);
         createAttentie.setInitialHeight(450);
         createAttentie.setTitle("Nieuwe Attentie Aanmaken");
         createAttentie.setContent(content);
         createAttentie.show(target);      
   }

问候，瑞克

您的堆栈跟踪表明ModalWindow createAttentie在您的代码尝试呈现时不属于页面。

跟踪页面构造逻辑和组件结构，确保所有内容都正确连接在一起。
