>      Project: NHibernate
>         Type: Bug
>   Components: Core
>     Versions: 1.0.2, 1.0.3
>     Reporter: Ka Man Tong
>      Fix For: 1.2.0.Beta3
>  Attachments: Account-orig.hbm.xml, Account.cs, Account.hbm.xml
>
> I have over 200 fields defined for a table accessing MSSQL 2000.
> Some fields have similar prefix (accountId, accountNumber, accountCategoryCode, etc) and I can see NHibernate generate the retrival SQL using the same prefix with some additional numbers and underscore as the column alias.
> All fields are in Int32, except one which is of String type.
> When retrieving, I got Number Format Exception when NHibernate tries to read some Int32 fields.  As I suspect that it was the Nullable issues and I have changed all Int32 fields to NullableInt32.  However the case is still the same.
> The field mapping XML is defined without any particular order of the fields.
> But when I tried to group all AccountXXX fields at the top of the mapping XML, the Number Format Exception doesn't appear anymore.
> Is the field mapping ordering important?
