[Mono-dev] Bug in XMLSerialization

[schneider at jsschneider.de]

Hi all,

I think I found a nasty bug in Mono's XML Deserialisation Module. I'm
trying to call a Webservice that returns a data strucutre containing an C#
enum. When I'm calling the service i get an error with the stacktrace
following this text. I need to get this fixed quickly, so i tried it this
way instead of submitting a bug ticket (but of course i will do this
later). MS CLR doesn't seem to have any problems with the call, so I
assume it's a mono bug.

Cheers,

Johannes

Enum looks like this:

[System.Xml.Serialization.SoapTypeAttribute("STATUS", "http://www.xxx")]
    public enum ACCOUNT_STATUS {
        
		/// <remarks/>
		ACCOUNT_ANY,

        /// <remarks/>
        ACCOUNT_NOSTATUS,

        /// <remarks/>
        ACCOUNT_INUSE,
        
        /// <remarks/>
        ACCOUNT_DELETED,
        
        /// <remarks/>
        ACCOUNT_RESERVED,
        
        /// <remarks/>
        ACCOUNT_ONHOLD,
        
        /// <remarks/>
        ACCOUNT_CANCEL,
        
        /// <remarks/>
        ACCOUNT_ACTIVE,
    }
