Primefaces：对话框隐藏时不更新文本字段

Question

我试图从对话框中更新文本字段。文本字段位于父组件中。但没有发生。如果我在更新命令按钮时给出文本字段的ID。我遇到的错误： javax.faces.FacesException：无法找到标识“customerCode”组件从“TabView的：lkpSltRec”引用

既然是无法找到组件的id。我已经使用了替代方案。我点了隐藏字段。单击命令按钮后，隐藏字段被更新，并通过简单的JavaScript函数更新父组件的文本字段。在对话框的命令按钮的oncomplete中调用javascript函数。因为，根据项目要求，我必须通过primefaces而不是通过javascript来实现它。 Plz，建议我在primefaces中的方法。下面的代码片段：

Answer 1

最后，我已经得到了解决方案。我遇到的例外是因为表单标签。在这种情况下，使用： ：＃{p：component（'componentId'）}

在这里它会搜索id不仅在形式，但在它之外。
