https://bugzilla.novell.com/show_bug.cgi?id=645553#c0 Summary: Empty ArrayList returned from WCF fails to deserialize, fixed in Mono need fix applied to MonoTouch Classification: Mono Product: MonoTouch Version: unspecified Platform: x86 OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Class Libraries AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: Customer Blocker: --- Description of Problem: Atsushi Eno fixed this error in the Mono svc. The bug still exists in MonoTouch SDK version 3.2. http://go-mono.com/forums/#nabble-td1576794 ---Summary from forum--- I am using a basicHttpBinding to communicate with an IIS 7 hosted WCF service from a WinForms ported application (running on Mono 2.6.1). If the WCF Service returns an empty array or an object containing an empty array the call results in the following exception: Exception in async operation: System.InvalidOperationException: Failed to set va lue of type System.Collections.ArrayList for property MonoTest.SearchService.DAS earchField[] Fields ---> System.ArgumentException: failed to convert parameters at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invoke Attr, System.Reflection.Binder binder, System.Object[] parameters, System.Global ization.CultureInfo culture) [0x00000] in <filename unknown>:0 .. The error goes away if I return null instead of the empty array. Patch to mono was applied here: http://lists.ximian.com/pipermail/mono-patches/2010-March/167770.html Steps to reproduce the problem: 1. Return an EMPTY ArrayList from WCF. 2. Consume WCF in MonoTouch by exporting WSDL to Proxy using SL3 SDK. Actual Results: xception in async operation: System.InvalidOperationException: Failed to set va lue of type System.Collections.ArrayList for property MonoTest.SearchService.DAS earchField[] Fields ---> System.ArgumentException: failed to convert parameters at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invoke Attr, System.Reflection.Binder binder, System.Object[] parameters, System.Global ization.CultureInfo culture) [0x00000] in <filename unknown>:0 Expected Results: Array that is empty should have been initialized.
