Make field mandatory depending on something else

[amacqueen]

I know I can use UI Policies to make a field mandatory based on certain conditions however i need to make a field mandatory the next time a form is opened and can't make it work.

Scenario is I am building a bespoke change application for a part of our business and once the change manager assigns the change to an individual I want the development field (u_development) to become mandatory only once the form is saved. I don't want the change manager to have to update the u_development field which is what a UI Policy enforces.

Can I achieve this?

Many thanks
