我不知道如何在更新或进程中引用复合组件的后代组件(别名呈现或执行).
我有这个复合组件resources / components / crud.xhtml：

AVVERTENZA: PWC4011: Unable to set request character encoding to UTF-8 from context /epcsdb,because request parameters have already been read,or ServletRequest.getReader() has already been called INFO: Skipping call to libraryExists(). Please set context-param com.sun.faces.enableMissingResourceLibraryDetection to true to verify if library http://java.sun.com/jsf/composite/components actually exists INFO: Cannot find component with identifier "itemForm:itemCrud:table:newButton" in view. INFO: Cannot find component with identifier "itemForm:itemCrud" in view. INFO: Cannot find component with identifier "editDialog" in view. INFO: Cannot find component with identifier "trashDialog" in view. INFO: Cannot find component with identifier "itemForm:itemCrud:j_idt34" in view.
结果是没有使用任何ajax调用更新任何组件.我不明白为什么找不到“itemForm：itemCrud：table：newButton”.它仅以process =“@ this”引用.
我正在使用primefaces 3.0.RC1-SNAPSHOT和Mojarra 2.1.3_01.
