我在我的plone網站上集成了collective.documenviewer。這用於在線查看PDF和其他辦公文件。Plone/Python：在Ubuntu上使用Plone的zc.async問題
其中一個可選的附加產品是plone.app.async，它反過來使用zc.async。現在，安裝順利進行，沒有錯誤。但是，當我保存文件時，會產生一個錯誤，我想不通：下面是錯誤：
2012-08-29T12:52:03 ERROR collective.documentviewer Error using plone.app.async with collective.documentviewer. Converting pdf without plone.app.async...
Traceback (most recent call last):
File "/home/frank/apps/myplonesite/plone/eggs/collective.documentviewer-2.2a1-py2.7.egg/collective/documentviewer/async.py", line 143, in queueJob

File "/home/frank/apps/myplonesite/plone/eggs/collective.documentviewer-2.2a1-py2.7.egg/collective/documentviewer/async.py", line 50, in __init__
self.queue = self.async.getQueues()['']

File "/home/frank/apps/myplonesite/plone/../../python27/lib/python2.7/UserDict.py", line 23, in __getitem__
raise KeyError(key)
KeyError: 'zc.async'
這些是我使用的版本：
plone.app.async = 1.2
zc.async = 1.5.4
我如何消除KeyError問題？
UPDATE：下面是我的擴建

看着回溯，他只是試圖與collective.documentviewer集成。他不應該閱讀文檔實際上是使用異步隊列 - 只需設置它。 – vangheem
@vangheem設置zc.queues不應該由插件完成，如果你這樣做，你應該改變它。這是由zcml故意發生的。 – ggozad
