I Have been upgrading the javascript api from 1.5 to 3.1 and having problems with symbols...
I am getting an error
"Microsoft Jscript runtime error: 'esri' is undefined
Also getting a 404 on a particular js file in the api library...
when i debugged in IE,
URL http://serverapi.arcgisonline.com/jsapi/arcgis/3.1/js/esri/symbol/Symbol.js
Method   GET
Result 404
Type text/html
Received 184 B
Taken  156 ms
Initiator <script>
Any suggestions on this....
Thanks in advance,
