我遇到了Primefaces框架的p：textEditor组件问题。 上下文菜单显示一个p：对话框，允许您在初始化有问题的p：textEditor中输入文本。 我在使用Primefaces框架的p：textEditor组件时遇到了问题。 上下文菜单显示一个p：对话框，允许您在初始化有问题的p：textEditor中输入文本。 谢谢你的帮助。

这是我的代码和之后导致的错误：

      <p:contextMenu beforeShow="pageC()">     
                <p:menuitem value="Ajouter une note" 
                            actionListener="#{noteManagerBean.nouvelleNote()}"   <----------

答案 0 :(得分：2)

代码中的问题是doubleMe [] => [] doubleMe (x:xs) => (2*x) : doubleMe xs 会引发noteManagerBean.noteSelectionnee.texte。发生这种情况是因为javax.el.PropertyNotFoundException返回空值。我想首次加载页面时会出现错误，因此您应该将文本编辑器的标记代码更改为：

getNoteSelectionnee()

这样，在设置 <p:textEditor id="idTexte" value="#{noteManagerBean.noteSelectionnee.texte}" placeholder="Entrez votre texte ici" height="129" style="..." rendered="#{not empty noteManagerBean.noteSelectionnee}" > 之前，不会失败。
