If I am understanding it correctly, you are using map.graphics.add to add the school graphics to map. Is that correct?

I think that MapImageLayer is using the functionality provided by Dynamic Layer of the Map Service. Because of which you are able to change the symbology, label and other details of a MapService. It is similar to LayerDrawingOptions in 3.x version. I couldn't find any documentation though. I checked the service used in the sample and they have the Dynamic Layer support enabled. Its worth a try. ... View more

If you want to reatain the scope to be you module. you need to use 'lang.hitch' all the place, where the scope might change, all callback functions. ... View more

Prasad, I cannot give you a solution, without knowing what the problem is. All I am saying is the "Unexpected token < ..." error occurs when the server returns html instead or JSON. The "<" is not a valid in JSON, but it is used in HTML to begin a tag. The html can be anything from 'server not found' 404 or 'service unavailable' 503 etc. You need to open the browser's developer window and look through all the requests sent, as well as response received. See if it contains any HTML response out of the ordinary. That will give is a clue what might be the cause of the problem. Hope this was helpful. ... View more
