Can't get max/min scale dependency from layer object

[Anonymous User]

Hi all,

I create a new layer group with this -

layers = new esri.layers.ArcGISDynamicMapServiceLayer("http://...");

The problem is it's not creating a dynamic layer so I can't get the scale dependency properties.  It's just a regular layer object.  I can get name, defaultvisibility but that's about it.

How do I create a dynamic layer?

Thanks
