在基于 z3c.form 的表单 updateWidgets() 上引发 ComponentLookupError

Question

仅在删除<includeDependencies package="." />后，我才在运行测试时遇到此问题<includeDependencies package="." /> <includeDependencies package="." />指令来自我的configure.zcml文件：

Error in test test_get_load_action (sc.embedder.tests.test_content.MultimediaTestCase)

以前工作的相同版本； 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" />

根据文档，这是由于迁移不良导致的已知问题，但事实并非如此。

我正在 Plone 4.2.6 下进行测试。 正如您在 CI 构建中看到的那样，相同的代码在 Plone 4.3 下工作并通过测试。

似乎我在 configure.zcml 声明中缺少一个包； 现在它看起来像这样：

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

现在正在工作： https : //travis-ci.org/simplesconsultoria/sc.embedder/builds/126432050
