My apologies for a probably obvious problem. I've got an example where I need to check (on update) if this object is actually being 'moved' (ie, keypair is being changed), and if there is already data at the dest. keypair, go back to the page, display both objects and confirm the user wants to overwrite the actual data there. If confirmed, null out the old keypair data and update the new keypair.
Now, I'm confused on where I should put the logic for all this? This almost seems like the perfect place for custom Validation code, and seems like something the Controller would do, but it also seems that this is business logic and shouldn't be coupled to Struts. I'm thinking that all Struts should call is my DTO.Update() method?
Maybe because I don't have much so-called business logic in this application that I'm not sure of what really should be in that layer, the above example is about as complex as the logic gets for me.
Thanks,
- Nic.
