GenericSetup controlpanel.xml allows configlets to be registered with translated titles (i18n:attributes="title"). This works in multilingual sites and Site Setup on classic UI show translated configlets.

However using ZMI/portal_controlpanel/manage_editActionsForm breaks translations here:

Products.CMFPlone/src/Products/CMFPlone/PloneControlPanel.py

Line 174 in 6212f6f

name = str(properties.get("name_%d" % index, ""))

The zope.i18n.message.Message is replaced with a plain str.

This PR fixes the issue by restoring the i18n Message from the stored action if there is no change to the name.

Closes #4344

@szakitibi thanks for creating this Pull Request and helping to improve Plone!

TL;DR: Finish pushing changes, pass all other checks, then paste a comment:

@jenkins-plone-org please run jobs

To ensure that these changes do not break other parts of Plone, the Plone test suite matrix needs to pass, but it takes 30-60 min. Other CI checks are usually much faster and the Plone Jenkins resources are limited, so when done pushing changes and all other checks pass either start all Jenkins PR jobs yourself, or simply add the comment above in this PR to start all the jobs automatically.

Happy hacking!
