ComponentLookupError在基于z3c.form的表单updateWidgets()上提出

Question

只有在我从我的<includeDependencies package="." />文件中删除了configure.zcml指令之后，我才会在运行测试时遇到这个问题：

Error in test test_get_load_action (sc.embedder.tests.test_content.MultimediaTestCase)
Traceback (most recent call last):

以前工作过的版本是相同的；当前的configure.zcml现在包括以下内容：

<include package="Products.CMFCore" file="permissions.zcml" />
<include package="plone.app.dexterity" />
<include package="plone.app.dexterity" file="meta.zcml" />
<include package="five.grok" />

根据文件 --这是一个已知的问题，因为迁移不好，但事实并非如此。

我在Plone 4.2.6下进行测试。在plone4.3下通过的代码和测试与您可以在CI构建中看到相同。

似乎我在configure.zcml声明中缺少了一个包；现在看起来如下所示：

<include package="Products.CMFCore" file="permissions.zcml" />
<include package="plone.app.dexterity" />
<include package="plone.app.dexterity" file="meta.zcml" />
<include package="collective.dexteritytextindexer" />
