Question

你知道为什么我的应用程序会抛出这个异常：

WARNING: /myProfile.xhtml @71,27 target="#{profileBean.selectedUser}": Property 'selectedUser' not found on type bg.fmi.master.thesis.beans.ProfileBean
javax.el.PropertyNotFoundException: /myProfile.xhtml @71,27 target="#{profileBean.selectedUser}": Property 'selectedUser' not found on type bg.fmi.master.thesis.beans.ProfileBean
---
Caused by: javax.el.PropertyNotFoundException: Property 'selectedUser' not found on type bg.fmi.master.thesis.beans.ProfileBean

当我在我的bean中有这个属性时：

@ManagedBean(name = "profileBean")
public class ProfileBean implements Serializable {
    private TUser selectedUser = new TUser();

    public TUser getSelectedUser() {
        return selectedUser;
    }

    public void setSelectedUser(TUser selectedUser) {
        this.selectedUser = selectedUser;
    }

.xhtml代码是这样的：

      <p:dataGrid var="user" value="#{profileBean.userList}">
                            <p:panelGrid columns="2">
        ....
        <p:commandButton id="submit" value="Save changes" actionListener="#{profileBean.editUser()}" >
           <f:setPropertyActionListener target="#{profileBean.selectedUser}" value="#{user}" />
        </p:commandButton>
  </p:dataGrid>

提前致谢！

我根据您的示例代码制作了一个简单的项目。

<h:form>
    <p:commandButton id="submit" value="Save changes" actionListener="#{profileBean.editUser()}" >
       <f:setPropertyActionListener target="#{profileBean.selectedUser}" value="#{user}" />
    </p:commandButton>
</h:form>

没有描述的错误。你的问题来自其他地方。删除不必要的位并尝试隔离问题。您可以更改属性的名称，并查看错误是否反映了新名称。确保你没有另一个同名的bean。

javax.el.PropertyNotFoundException：在类型bg.fmi.master.thesis.beans.ProfileBean上找不到属性'selectedUser'
