On the first of May, Community Commons 4.3.4 was released. The notification is still visible in the Dev Center notifications list: Community Commons Function Library from the AppStore has been updated. Community Commons Function Library has been updated to version 4.3.4 . The new version is compatible with Mendix 5.1.1 and contains the following changes: Fixed cloning with autonumber fields. However, the latest version in the App store is 4.3.3. Once again I have to manually fix the Clone function in every project I'm using Community Commons. :-( Why? Ticket: 100739
I'm not sure where version 4.3.4 went, but version 5.0 has just been released. That version should also contain the fix you need.
