In a JSAPI map app that consumes a dynamic map service as LeatureLayers, when you do a continuous zoom (e.g., with the track wheel, an Apple MagicMouse, or in a pinch-zoom on a tablet), the feature disappears until zooming ends, and then the featurelayer draws to the extent zoomed to.
Compare this with a dynamic map service layer, which maintains the raster graphic rendering of the layer until zooming stops, at which point the new raster is drawn.
My question: Is it possible to maintain a visual on the FeatureLayer during the continuous zoom?
TIA
