WcfProxy - NullReferenceException

Fabiano posted on Friday, November 23, 2012

Hi all,

If error occurs in the WcfService the SL client throws a NullReferenceException.

Following the WcfProxy code at line number 645 is the code below:

try

{

Csla.WcfPortal.

WcfResponse response = null;

if (e.Error == null)

response = ConvertResponse(e.Result);

var globalContext = (ContextDictionary)MobileFormatter.Deserialize(response.GlobalContext); ----> if e.Error != null response is always null

so the NullReferenceException is raised.

May I use the work around below?

var globalContext = response == null ? ApplicationContext.GlobalContext : (ContextDictionary)MobileFormatter.Deserialize(response.GlobalContext);

Best regards,

Same problem for me, my service was misconfigured:

In case this help someone else until the fix is released, I personally updated (take care to update all Create/Fetch/Update/Delete):

if (e.Error == null)

response = ConvertResponse(e.Result);

var globalContext = (ContextDictionary)MobileFormatter.Deserialize(response.GlobalContext);

into:

ContextDictionary globalContext = null;

if (e.Error == null) {

response = ConvertResponse(e.Result);

globalContext = (ContextDictionary)MobileFormatter.Deserialize(response.GlobalContext);

}
