Describe the bug

when I set 'self.page.dialog = self.success', env though success.open is false,it will show a alertdialog. image

Code sample

Code ```python [Paste your code here] class success_alert(ft.AlertDialog): def __init__(self,page): super().__init__() self.modal = True self.page = page self.title = ft.Text("操作成功") self.actions = [ ft.TextButton("确定", on_click=self.close_dlg), ft.TextButton("取消", on_click=self.close_dlg), ] self.actions_alignment = ft.MainAxisAlignment.END def close_dlg(self,e): self.open = False self.page.update() class function_container(ft.Container): def __init__(self,page): super().__init__() self.add_user_alert = add_user_Alert(page) self.content = ft.Row( alignment=ft.MainAxisAlignment.CENTER, spacing=25, controls=[ ft.ElevatedButton("添加用户",on_click=self.add_user ), ft.ElevatedButton("返回登录界面", ), ft.ElevatedButton("备份", ), ] ) def add_user(self,e): self.page.dialog = self.add_user_alert self.add_user_alert.open = True self.page.update() class add_user_Alert(ft.AlertDialog): def __init__(self,page): super().__init__() self.modal = True self.success = success_alert(page) self.title = ft.Text("请输入待添加人员的消息") self.id = ft.TextField(hint_text="请输入账号", autofocus=True) self.name = ft.TextField(hint_text="请输入姓名", autofocus=True) self.password = ft.TextField(hint_text="请输入密码", autofocus=True) self.admin = ft.TextField(hint_text="请输入身份，1为普通，0为管理员", autofocus=True) self.content =(ft.Container(ft.Column(controls=[self.id,self.name, self.password, self.admin]))) self.actions = [ ft.TextButton("确定", on_click=self.certain_dlg), ft.TextButton("取消", on_click=self.close_dlg), ] def close_dlg(self,e): self.open = False self.page.update() def certain_dlg(self,e): register_sql = f"insert into card values({int(self.id.value)},'{self.name.value}',0,'{self.admin.value}','{self.password.value}') " root_cursor.execute(register_sql) root_db.commit() self.id.value = None self.name.value = None self.password.value = None self.admin.value = None self.close_dlg(e) **self.page.dialog = self.success # this point self.page.update()** ```
