Thanks for the response. So I guess in short, the answer is - no validation is provided out of the box on the admin side of the CMS... Yet. Although it can be done - it wasn't for various reasons.
Okay, well, that is not so bad, surprising yes... "Content Management the way it was supposed to be?", "Websites humans can use".. hmm not quite ...
For such a wicked job in so many, and I mean many areas, making an assumption that an admin user doesnt make mistakes is kinda like saying, "need a database driven cms - use phpmyadmin". Still, I will see what I can do with the jquery validation plugin, or other approach.
Thanks though for taking the time to respond, very appreciated.
@SilverRay: Thanks for the reply.
In creating a page that already has an existing url, yes, it is correct that the cms appends an incrementing integer to the end of the URL, but you can still change it back to conflict with an existing name and receive no warning at all, eg. Change home-2 to home and then save.
So, essentially the SS CMS comes with absolutely no field validation out of the box at all at version 2.2.2.
At least thats confirmed. Cheers.
