I am just getting started with learning Dojo and ArcGIS API so please bear with me.
I have an existing prototype of an application that use ArcGIS version 3.5. I am looking at the navigation toolbar sample https://developers.arcgis.com/javascript/jssamples/toolbar_navigation.html and trying to get the Prev Extent and Next Extent functionality work in my application. This sample uses ArcGIS V 3.8. When I copy this sample code and run it locally it works. However since I use V3.5 I changed the below line in this sample and it stopped working.
<script src="http://js.arcgis.com/3.8/"></script>
<script src="//serverapi.arcgisonline.com/jsapi/arcgis/3.5"></script>
Is this feature only supported in V3.8? How do I get it work with V3.5?
