Question

我想将自定义验证器附加到复合组件内的一个输入字段，但验证器根本不会触发。我完全按照here所描述的那样完成了，但我无法让它发挥作用。同样在我的代码中，对复合组件输入验证器（function CreateMyCustomUserDialog(): Boolean; var Form: TSetupForm; OKButton, CancelButton: TNewButton; Label1: TLabel; Edit1: TEdit; begin Form := CreateCustomForm(); try Form.ClientWidth := ScaleX(256); Form.ClientHeight := ScaleY(256); Form.Caption := 'User Information'; Form.CenterInsideControl(WizardForm, true); OKButton := TNewButton.Create(Form); OKButton.Parent := Form; OKButton.Width := ScaleX(75); OKButton.Height := ScaleY(23); OKButton.Left := Form.ClientWidth - ScaleX(75 + 6 + 75 + 10); OKButton.Top := Form.ClientHeight - ScaleY(23 + 10); OKButton.Caption := 'OK'; OKButton.ModalResult := mrOk; Label1 := TLabel.Create(Form); Label1.Parent := Form; Label1.Alignment := taCenter; Label1.Caption := 'Username:'; Label1.Width := Form.ClientWidth; Label1.Height := ScaleY(23); Label1.Top := 30; Edit1 := TEdit.Create(Form); Edit1.Parent := Form; Edit1.Top := 50; Edit1.Width := 100; Edit1.Left := (Form.ClientWidth - Edit1.Width) / 2; Edit1.Text := 'Admin'; CancelButton := TNewButton.Create(Form); CancelButton.Parent := Form; CancelButton.Width := ScaleX(75); CancelButton.Height := ScaleY(23); CancelButton.Left := Form.ClientWidth - ScaleX(75 + 10); CancelButton.Top := Form.ClientHeight - ScaleY(23 + 10); CancelButton.Caption := 'Cancel'; CancelButton.ModalResult := mrCancel; CancelButton.Cancel := True; Form.ActiveControl := OKButton; if Form.ShowModal() = mrOk then MsgBox('You clicked OK.', mbInformation, MB_OK); finally Form.Free(); end; end;）的引用标记为红色for="validateService"。我做错了什么？

component.xhtml

cannot resolve symbol 'validateService'

page.xhtml

<cc:interface>
    <cc:attribute name="service"/>
    <cc:editableValueHolder name="validateService" targets="#{cc.attrs.service}"/>
</cc:interface>

我通过直接在复合pomponent输入字段中添加验证器来解决它，如此

<p:inputText id="service"
             validator="serviceValidator"/>

但我仍然不知道为什么上述解决方案无效。

为什么未解析复合组件验证器的引用？
