I can see already it doesn't like the CodeMode and row/object so these might be added in later versions only...? Anything I can do here to make it work for 2008 version (besides migrating to a newer version of Cachce)?

I did try your solution in Cache 2008. When I enter the Audit class in Studio it is all good, can save and compile alright. However, when I try to put in the AuditBase class I get loads of errors relating to 'Unknown Trigger Keyword'... what is wrong here? Is this to do with the version of Cache?

Thanks in advance, Rene.
