The following things are missing to enable a non-technical person to set up replication in iDempiere.
1. The plugin.xml isn't defined for org.adempiere.model.ExportModelValidator. It's supposed to be in org.adempiere.replication plugin.
2. The replication strategy field isn't visible on the Client form.
3. The model validator in point 1 must be defined on the client. This was previously done on the client form. This field is now hidden.
3.1 I assume that all model validators are supposed to be defined in the window "Model Validator". However in the current setup those can only be defined as global when logged in as SuperUser.
