jsf-2 - 动态渲染 - 无法找到具有 clientId 的组件

Question

我正在将 xhtml 渲染到一个对话框，该对话框的组件是使用 Dynamic example 从服务器端动态添加的。 .

使用 PrimeFaces 5.1、JSF 2.1 Mojarra 和 tomcat 7。

当我单击弹出窗口的关闭按钮时，在 Eclipse 控制台中会看到大量无法找到该组件的情况，因此关闭操作响应缓慢。

尝试将 myForm 上的 prependId 更改为 true。还尝试将关闭按钮的 update 属性中的 @form 替换为 :myForm。 这两种方法都没有成功。

我想知道如何防止触发此无法找到组件。

MyViewBean 动态渲染代码 - 单击编辑按钮时触发

HtmlPanelGroup panelGroup = new HtmlPanelGroup();
panelGroup.getChildren().clear();
TabView tabView = new TabView();
Tab sectionTab = (Tab) tabView.findComponent("sec_" + question.getSectionId());
sectionTab.setId("sec_" + question.getSectionId());
sectionTab.setTitle(question.getSectionName());

HtmlPanelGrid pg = new HtmlPanelGrid();
pg.setColumns(3);

OutputLabel questionText = new OutputLabel();
questionText.setValue(question.getTitle());
pg.getChildren().add(questionText);

OutputLabel coln1 = new OutputLabel();
coln1.setValue(":");
pg.getChildren().add(coln1);

final String respBind = "#{myViewBean.questionResponse[\""+ question.getId()+ "_"+ pet.getId()+ "_"+ question.getMultiPet() + "\"]}";
final ValueExpression resp = FacesContext.getCurrentInstance().getApplication()
                                .getExpressionFactory().createValueExpression(FacesContext.getCurrentInstance().getELContext(), respBind,   String.class);
InputText value = new InputText();
value.setId("iq_"+ String.valueOf(question.getId()) + "_"+ String.valueOf(pet.getId()));
value.setSize(20);
value.setValueExpression("value", resp);

pg.getChildren().add(value);

sectionTab.getChildren().clear();
sectionTab.getChildren().add(pg);
tabView.getChildren().add(sectionTab);
panelGroup.getChildren().add(tabView);

找到了这个问题的解决方案...要修复“无法找到带有 clientId 'tab:j_id16:sec_4' 的组件，无需删除它。”，我们必须将 jsf jar 从 2.1.7 更新到2.1.9 或至 2.1.29。 在下面的链接中，这被报告为 Mojarra 的问题。
