Evolutility

I'd like to pre-opoulate a LOV list with the current user.

I'm using Evolutility to build a simple helpdesk system but want to pre-populate the current user from a LOV value.

I have an LOV column listing all users and can pre-populate it using the default="123" method.

How do I dynamically place the 123 though?

Also if I make this field read-only it no longer follows the default rule...
