           Summary: Cursor does not function properly when using linking
    Classification: Mono
           Product: MonoDroid
           Version: unspecified
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Critical
          Priority: P5 - None
         Component: Runtime

I have created a custom SimpleCursorAdapter and have overridden the NewView and
BindView methods in order to format some of the text that is displayed in the
resulting view. Everything works without issue when using no linking. However,
when I attempt to run the application with linking, the cursor (in the context
of the adapter) does not appear to function normally.

Reproducible: Always

Actual Results:  
If running against Android 2.2, the GetColumnIndex/GetColumnIndexOrThrow
methods always return 1 and all resulting Get methods (e.g. GetLong, GetInt,
GetString, etc.) fail to return any data. 

If running against Android 2.3.3, whenever the
GetColumnIndex/GetColumnIndexOrThrow methods are called, I receive the
following exception: 

E/mono    (  347): Unhandled Exception: System.NullReferenceException: Object
reference not set to an instance of an object 
E/mono    (  347):   at (wrapper delegate-invoke)
E/mono    (  347):   at Android.Runtime.JNIEnv.CallIntMethod (IntPtr jobject,
IntPtr jmethod, Android.Runtime.JValue[] parms) [0x00000] 
E/mono    (  347):   at Android.Database.ICursorInvoker.GetColumnIndexOrThrow
(System.String columnName) [0x00000] 

Expected Results:  
Cursor should return data without issue.

Using Monodroid v1.9.2
