Using multilingual associations, select an article and then Copy Reference to Target and save the target
also the acl permission setting are copied
the acl permission setting are not copied
I understand it is very complicated to implement. And I confirm that also batch copy does not keep acl permission setting as we already know.
No Code Attached Yet
save2copy does not indeed copy permissions, wherever the function is used (multilingual associations or not).
We also do not have among batch functions the possibility to batch keep or change permissions.
Until someone work on this, these are known aspects of J.
As far as I know, nobody proposed a solution for this bug/lack of feature.
So, yes, I would keep this open.
