While migration of a Plone 4.3.18 site with bda.plone.shop to our docker environment, I found collective.z3cform.datagridfield in a confusing state.
Now it is fixed. If you use it in Plone 4.3 use fresh released version 1.3.1.
Otherwise for Plone 5 there is a fresh version 1.4.0 released.
I hope all is fine with those...
Plone 5.2/Python 3 changes are still pending in PR 79. A rebase is needed, more work too and tests should go green.
Help appreciated! This is probably a low hanging fruit for the Plone Tagung Sprint. Any takers?
