Relations: Plone fails to start up when plone.app.iterate is missing #462

Closed mauritsvanrees closed 2 years ago

mauritsvanrees commented 3 years ago

The recently added relation module has an undeclared dependency on plone.app.iterate. When starting up Plone 6 with only Products.CMFPlone, I get an error:
