Sys.WebForms.PageRequestManager null or not an object

Dec 12, 2009 at 8:18 PM

Using .net framework 3.5. Have a scriptmanager on the master page. Added the artem google maps control and get a runtime error

"Sys.WebForms.PageRequestManager null or not an object"  when it tries to execute javascript.

Have tried the usual suspects

1. Ajax web config settings are present.

2. XHTMLConformance setting is not present in web.config.

Anybody seen the same error or have any insight?

Thanks
