The cause is that there are wrappers without a type. This problem does not occur in TL 6, where every wrapper still has a type.

Solution

The class is deleted and replaced with the existing class `tl:TypeInstanceListModelBuilder` from the same package. This class does not have the problem.

Code Migration

Locate the MEInstanceTableModelBuilder class. Replace all instances with the tl:TypeInstanceListModelBuilder class. This class is located in the same package. Replace the name of the Config property metaElement with meta-elements. See, for example: [320926]

Test

Edit something in the "Role Profiles" view and save it. No errors should appear in the log.
