Normalization (training) with clustering (group model) does not work as expected

Using a Normalization operator alongside k-Means operator to create a group model within a Cross-Validation or Split-Validation does not work because the Performance (Cluster Distance Performance) operator expects a CentroidClusterModel but instead received a GroupedModel. It seems that the Performance (Cluster Distance Performance) operator needs to be updated to accommodate a grouped model.
A simple example using the Iris dataset in the RapidMiner Samples directory is attached showing the issue.
