Derek, that bit where you mention hooking "run-time" validation to be saved, is pretty much what I’m doing in my post. You need to consider that you might not have a complete record to insert, but one field at the time, hence why I create the ‘updateTableService()’. From what I understand, the only difference between what you suggest and what I did, is that on my code, the validation is fully done on the server side. The advantages are that I can apply validators such as ‘isUnique’ (among others that require the DB access) as well enforce input validation (from a security standpoint, there is no such thing as client-side input validation). The downside is obviously performance whenever things don’t even need to reach the server-side and parsley is able to do them immediately within the browser.
I guess I could add parsley to get the best of both worlds...
