[Mono-dev] Help with xsp

[Neale Ferguson]

At the bottom is the minimal test case that results in the error. If you
rename the 2nd testIt to something else and get rid of the (MessageName...),
there's no problem.

Would someone try it on there platform to check that it's not something I've
done on my system? 

The problem appears to be when
System.Web.Services.Description.BasicProfileChecker.CheckR2305 invokes
System.Web.Services.Description.MessageCollection.get_Item using the string
"TestInt". The IndexOf comes back with -1 which triggers the throw. The call
to IndexOf is:

[  6] . . . . . . ENTER:
System.Web.Services.Description.MessageCollection:IndexOf
(System.WebDescription.Message) ip: 0x3ffd725d0ac sp: 0x3fff4b13a98 -
this[MONO_TYPE_CLASS]: 0x3ffd767ae3:null],ECTT


                public Message this [int index] {
                        get {
                                if (index < 0 || index > Count)
                                        throw new
ArgumentOutOfRangeException ();

                                return (Message) List [index];
                        }
                        set { List [index] = value; }
                }

                public Message this [string name] {
                        get { return this [IndexOf ((Message) Table
[name])]; }
                }

The trace shows:

[  6] . . . . . . ENTER:
System.Web.Services.Description.MessageCollection:IndexOf
(System.WebDescription.Message) ip: 0x3ffd725d0ac sp: 0x3fff4b13a98 -
this[MONO_TYPE_CLASS]: 0x3ffd767ae3:null],ECTT

As far as I can see from the trace, List.Insert is never called to put
things into the table.
