Published ESRI layer scale dependency problems

I have published a layer with 3 scale dependency settings so regardless of the scale one of the three layers should be visible at any one time.

When I view the layer using the "View In: ArcGIS JavaScript" link (from the ArcGIS REST Services Directory page) the layer works correctly, I zoom in and out and the features are rendered correctly.

When I then switch to my development map and include the layer in the map layers list and load the map up, the layer appears on the zoomed out scale fine (global view). When I then zoom in past the threshold my layer completely disappears. If I inspect the JavaScript I can navigate to map.layers.item[x] and the visible property is set to true but the layer simply does not render on the map.

Does anyone have any idea what is going on?

Layer caching is disabled.

The only difference I can see between the ArcGIS JavaScript view and my development map is the layer is a FeatureLayer in my dev configuration.
