When customizing the Create Query-based Distribution Group Web Interface form within the Active Roles Web Interface, choosing Add Entry | Create results in the following error:
An error occurred during the last operation.
Error: Schema object name cannot be null or empty Parameter name: schemaObjectName
Some common attributes are available when choosing Select instead of Create. These can be added without error. If it is necessary to add a custom attribute or one not found on the Select screen, there is currently no workaround.
Waiting for fix in a future release of Active Roles.
