> Success callback for XHR to local file that doesn't exist on device never
> called.
> ---------------------------------------------------------------------------------
>
> Key: CB-7444
> URL: https://issues.apache.org/jira/browse/CB-7444
> Project: Apache Cordova
> Issue Type: Bug
> Components: WP8
> Affects Versions: 3.6.0
> Reporter: Vladimir Kotikov
> Assignee: Jesse MacFadyen
> Priority: Critical
> Labels: wp8, xhr, xhrhelper
> Fix For: 3.6.0
>
>
> XHR request for local file that doesn't exist on device causes a runtime
> exception:
> {noformat}
> An exception of type 'System.OutOfMemoryException' occurred in
> Microsoft.Phone.Interop.ni.dll but was not handled in user code
> {noformat}
> that catched in the XHRHelper code and {{__onXHRLocalCallback}} for this
> request is never called.
> *Repro steps:*
> 1. Create blank MDD app, add WP8 platform.
> 2. Try to get an unexistant file, e.g.:
> {noformat}
> var xhr = new XMLHttpRequest();
> xhr.open("GET", "../this.file.is.not.exists", true);
> xhr.onload = xhr.onerror = function() {
> console.log ('Callback called');
> }
> {noformat}
> *Expected:*
> 'Callback called' is printed to console
> *Actual:*
> No output in console.
> Problem is in arguments array, that passed to {{__onXHRLocalCallback}}. Seems
> that member of this array can't be null, so replace
> {noformat} new string[] { "404", null, reqId } {noformat}
> with {noformat} new string [] { "404", string.Empty, reqId }{noformat} solves
> the problem.
