Editor Widget and Clustering

I have run into an issue with the clustering function for a feature layer in Flex Viewer 3.1. I would like to cluster the feature layer and still be able to edit, but if several features are clustered, the edit tool is unable to select them and display the popup to allow attribute editing. This is a problem for features that have overlapping geometry, since you can't zoom in beyond their cluster scale.

Is this an expected behavior of clustering? Does anyone know a way around this?

Thanks for any suggestions!
