I am getting errors like the above for property 'role', 'group', and 'roleAndSubordinates' for multiple objects in my org when I attempt to deploy from Sandbox to Sandbox. Friday evening deployment went off without a hitch and this afternoon, after making some class and page changes, I get these errors and am unable to get my code moved.

Wy do I think this has something to do with Summer '11 arriving in my Sandboxes yesterday? Any idea how to fix it?

i am using apex class like this..follows

global class YodleeLoginService {
webservice static List<object> cobrandLoginContext(string username) {
    List<object> cobrandRespInfo = new List<object>();  
     
   yintegDomyexpensesCom.CobrandLoginServiceHttpSoap11Endpoint serviceobj=new yintegDomyexpensesCom.CobrandLoginServiceHttpSoap11Endpoint();
   
    serviceobj.endpoint_x='http://171.16.44.40:8081/YodleeIntegration/services/CobrandLoginService';
    
  
    yintegDomyexpensesComXsd.CobrandLoginResponse responseObj=new yintegDomyexpensesComXsd.CobrandLoginResponse();
     
     responseObj=serviceobj.loginCobrand(cobrandId, appId, cobrandLogin, cobrandPassword);
 
     //cobrandRespInfo.add(responseObj);
     
      String language=responseObj.language;
  
        return cobrandRespInfo;
   
}
    
}

/// Here how to return the object from the response or how to get the fileds value present in tne response

I am getting error like this...
