Hi Gene,

I see, sorry I didn't know you that you wanted to not commit to the DB.

For info on current, previous, g_scratchpad:

The Resolve Incident UI action is unique in that it works both client and server side.

So a few things to make it work the way you want.
If you get a chance I updated the button in this demo - https://demo014.service-now.com/nav_to.do?uri=sys_ui_action.do?sys_id=38c073d7465762820116c37c3353540f

You will want to comment out the part that executes on the server. Current is a server side. the g_form. is client side.

See the attached image for the parts to comment out.
