@tragicwhale i don't think there's option to load client script on the form for both...i guess you'd have to deploy both.

I havent tested it yet but I believe you can do this, have 2 client scripts deployed to one record and one being SS1.0 and the other being SS2.0. What you cannot do is have one script file have a combination of SS1.0 and 2.0 code.

yeah i guess that should work. i was thinking more on the form itself. so if you had 3 custom forms each with their own client script file attached.

yeah that will work- 3 different custom forms- all with its own client side script pf any flavour. That will work. I am sure you could potentially put 2 client scripts (one SS1.0 and one SS2.0) on ONE form and that will also execute.
