> Aggregator enricher lost on rebind (due to ClassCastException)
> --------------------------------------------------------------

> Key: BROOKLYN-569

> Reporter: Aled Sage

> I had an aggregator for {{systemload.average}} on the cluster. On rebind, it
> failed with the {{ClassCastException}} shown below. The consequence (I
> think?) is that the enricher is not added to the entity.
