i want to use latest dojo 1.9

I actually want o use DOJO 1.7

I am confused...

Is there a specific technical reason that makes Dojo 1.8 unattractive for use? You haven't posted any technical details.

If you need to use 1.7, you could probably use an older version of the Esri JSAPI that uses Dojo 1.7

I actually want o use DOJO 1.7 as it approved by our company but no dojo1.8 , yeah esri uses dojo1.8 but i we cannot use that but we can use ESRI only for ESRI related stuffs
