I have a Plone 4.3.2 site with plone.app.contenttypes and custom packages in src folder. When migrating to Plone 4.3.4, I run into error -- Bad constraint 4.3.4.1 Products.CMFPlone>5.0.dev0.
I guess the issue is from plone.app.event 1.2.7 requirement. After I pin p.a.event to 1.1.4, everything seems working, though I am not sure if this is a good solution.
This is a note for myself and hopefully useful for others.
I'm getting the same error on a site. plone.app.event is pinned to 1.1 but it still gives the same error. How did you go about identifying the bad package?
Thanks... @hvelarde and @thet
In my case it was due to a development version of plone.app.widgets, pulled in by mr.developer (I know I know, production sites shouldn't use mr.developer). The dev version did require Products.CMFPlone>=5.0.dev0. Using a packaged version of plone.app.widgets pinned to 1.7.1 fixed the issue.
