More Object Datasource

Ever encounter "Exception Details: System.InvalidOperationException: ObjectDataSource 'ods' could not find a non-generic method 'Update' that has parameters: ...." ? No kidding ?
I will not show you the hot water, people have already found it :
http://geekswithblogs.net/mnf/archive/2007/03/01/107642.aspx (the short version)
http://weblogs.asp.net/bradygaster/archive/2006/09/26/How-to-Bloody-Your-Forehead.aspx (the long story)
Just a hint - do not use "Use Optimistic Concurrency" !!!
And then you Should slightly modify the Auto-generated code for the ODS.
Well, it's not a good idea at all to mess with auto-generated code, but what else can we do?
Luckily, Microsoft has promised that this BUG is fixed for the next release of Visual Studio.
I wander how many additional bugs are there waiting to crash developer's work ;)
