I'm new in Widsets development, and would like to develop a widset that will need a token authenticaton in a httpservice. I tried to follow the example at http://dev.widsets.com/wiki/Token_authentication and I receive this error:
handleResponse: error: http.nourlconf/1: URL was not found in widgetconfig xml

I don't know what is causing this error and what to do. some where in the document it was mentioned that i need to specify a callbackUrl can this be the problem? and i don't know what to specify as callbackUrl?

Does someone know the process to implement Token autentication between widsets and a partner site?
