ValueError: Disallowed subobject type: Topic for Products.PressRoom Plone 4.3

Question

我在 Plone 4.3.7 实例上安装了 Products.PressRoom 3.3。当我尝试在站点根目录创建新闻发布室时，我得到 ValueError: Disallowed subobject type: Topic

Traceback (innermost last):

谁能帮我解决这个问题？

谢谢

Answer 1

从 Plone 4.2 开始，Topic 内容类型已被弃用。

所以你可以：

1. 启用旧样式 collections（就像您所做的那样），方法就是将其勾选为全局可添加。但是通过这种方式，您将在网站
中获得两个类型的collection
2. 修复 PressRoom 包以使用 Collection 而不是 Topic。如果幸运的话，它会简单地 "just works"。考虑将问题作为问题打开 project issue tracker 也
