I'm using a FeatureLayer to display features and show the infowindow, much like one of the samples. I would like to control where to display the infowindow and preferably use getInfoWindowAnchor, but with FeatureLayers, map.infowindow.show is never called, so I can't pass in the anchor. Is there any way to set the anchor to getInfoWindowAnchor for FeatureLayers?
