I tend to get better help here then the ESRI forum so...

Using http://developers.arcgis.com/en/javascript/sandbox/sandbox.html I was able to create a simple application which demonstrates that if you set a non-trivial lods on a map the basemap will not behave correctly (try zooming beyond level 15).

Any workarounds?

There's likely a bug here which I think we have a fix for in the next (3.5) release.

In the meantime, instead of using map.options.lods, try specifying minZoom and maxZoom to specify the range of levels you'd like your map to use.

  • This works but not for ArcGISDynamicMapServiceLayer as a base layer...can't set LODS on a dynamic layer? Setting both the map lods and the minZoom resolves this for dynamic and tiles layers.

    For a map with only dynamic layers, you'll have to use LODs. I've confirmed we've fixed this at 3.5 (due out in the next couple of days).
