Hi Experts,
Is there a way in Groovy to throw an error based on certain validations and close the prompt screen?
In my current application, I am using throwVetoException to trigger the error, but the prompt screen remains open. Is there a method to both throw the error and close the prompt screen?
In Calc Manager, the return function serves this purpose by displaying the error and closing the rule prompt screen. However, in Form 2.0, return behaves similarly to throwVetoException, displaying the error without closing the prompt screen.
