我更改了原型属性（字段）名称，现在我收到权限错误。我能做些什么？
我将内容类型中的属性（字段）命名为“字符串”而不是“公司”。
我已经安装了我的产品，看到此错误后，我在内容类型类中更改了它，重新安装了产品，运行更新安全设置并更新目录。但我不断收到：
Module Products.CMFPlone.utils, line 392, in _createObjectByType
Module Products.CMFCore.TypesTool, line 290, in _finishConstruction
Module Products.CMFCore.CMFCatalogAware, line 148, in notifyWorkflowCreated
Module Products.CMFCore.WorkflowTool, line 291, in notifyCreated
Module Products.DCWorkflow.DCWorkflow, line 346, in notifyCreated
Module Products.DCWorkflow.DCWorkflow, line 430, in _changeStateOf
Module Products.DCWorkflow.DCWorkflow, line 529, in _executeTransition
Module Products.DCWorkflow.DCWorkflow, line 389, in updateRoleMappingsFor
Module Products.DCWorkflow.utils, line 64, in modifyRolesForPermission
Module AccessControl.Permission, line 92, in setRoles
AttributeError: string
由于我已经从我的内容类型中删除了该字符串属性，因此如何删除该字符串属性？我已经重新安装了产品，重新启动了我的实例，但我仍然遇到同样的问题。有想法吗？我可以删除我的 Data.fs，因为它是开发计算机，但如果它发生在生产站点中，则这不是一个选择。
PS：当我运行 bin/instance fg 时：
2011-07-28 19:01:59 WARNING Init Class mynamespace.mypackage.content.mycontent.MyContent has a security declaration for nonexistent method 'string'
I named an attribute (field) in a content-type 'string' instead of 'company'.
I've installed my product and after seeing this error, I changed it in my content type class, reinstalled the product, ran update security settings and update catalog. But I keep getting:
Module Products.CMFPlone.utils, line 392, in _createObjectByType
Module Products.CMFCore.TypesTool, line 290, in _finishConstruction

Module Products.DCWorkflow.DCWorkflow, line 389, in updateRoleMappingsFor
Module Products.DCWorkflow.utils, line 64, in modifyRolesForPermission
Module AccessControl.Permission, line 92, in setRoles
AttributeError: string
How do I delete this string attribute that is persisted somewhere in ny ZODB since I've already removed it from my content type? I've reinstalled the product, restarted my instance, but I keep getting the same problem. Ideas? I can delete my Data.fs since it's a development machine, but if it happened in a production site, this wouldn't be an option.
PS: When I ran bin/instance fg:

我发现了问题。我更改了内容类，但没有更改内容类型界面。
paster也在interfaces.py上创建一个# -*- 模式定义在此处 -*-。我在我的产品目录中执行了grep string并找到了它。I found the problem. I changed in my content class, but didn't change in my content type interface.
pastercreates a# -*- schema definition goes here -*-oninterfaces.pyas well. I did agrep stringon my product directory and found it.
