Has anyone been able to make this work with the lastest JS API? I'm trying to make the sample work by only changing the api references and have started trying to convert the code, but am getting stumped pretty early.dojo.declare('esri.ux.layers.ClusterLayer', esri.layers.GraphicsLayer, {
is right at the top in the declaration of the class and it blows up thinking the GraphicsLayer is "null or undefined".Thoughts?
