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

Question

I'm having this issue while running tests only after I removed the <includeDependencies package="." /> <includeDependencies package="." /> directive from my configure.zcml file:

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

Same versions where working before; current configure.zcml now includes the following:

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

According to the documentation this is a known issue due to a bad migration, but this can't the case.

I'm testing under Plone 4.2.6. Same code works and tests pass under Plone 4.3 as you can see in the CI builds .

Answer 1

Seems I was missing a package on the configure.zcml declaration; now it looks like this:

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

and now is working: https://travis-ci.org/simplesconsultoria/sc.embedder/builds/126432050
