我们将JSF从2.1.6升级到2.1.22以解决此问题：JSF error - IllegalStateException: PWC3999: Cannot create a session after the response has been committed
它有效。但是JSF版本的更改引起了另一个问题：在视图中找不到某些组件，而GlassFish抛出了一个有两个例外的堆栈跟踪。第一个：
javax.faces.FacesException: Cannot find component with identifier ":previewForm" referenced from "indexForm:publicacoesDt:j_idt112".
at org.primefaces.util.ComponentUtils.findClientIds(ComponentUtils.java:271)

at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:905)
at com.sun.faces.renderkit.html_basic.HtmlBasicRenderer.encodeRecursive(HtmlBasicRenderer.java:312)
...
第二个：
PWC1406: Servlet.service() for servlet Faces Servlet threw exception
java.lang.IllegalStateException: CDATA tags may not nest
at com.sun.faces.renderkit.html_basic.HtmlResponseWriter.startCDATA(HtmlResponseWriter.java:664)

...
标识符为“indexForm：publicacoesDt：j_idt112”的组件是PrimeFaces的commandLink，“：previewForm”是JSF表单。当触发使用commandLink更新表单的commandButton时会发生此问题。但就在第二次提交中，第一次提交是成功的。
任何人都知道为什么会出现这个问题？
