Dear all,

This blog outlines the approach to implement modern-style custom pop-ups and error messages on the UI screen within the Advance Workflow product interface, similar to web or mobile applications for enhancing the user experience.

Kindly follow the steps provided below for implementation:

1) Create an HTML Content field from the Custom fields section, deploy it in your form and make Display as Only Value in the from designer.


Setup → FIELDS & FORMS → Custom Fields





2) Write a Groovy script as shown below for your button on-click event/on change of any custom field with the validation to perform.


Setup → DEVELOPMENT → Scripts


Code:
try
{
// Your block of code //
// Throw the error message you want to pop up on the screen in the validation block //
throw new Exception('Showing pop-up on screen.')
// Your rest of code //
}
catch(Exception e)
{
String msg=e
if(msg.equalsIgnoreCase('java.lang.Exception: Showing pop-up on screen.'))
{
String popUpMessage = "Showing pop-up on screen."
String errorBody = GetPopup(popUpMessage)
form.setValue('html_field',errorBody)
}
// Extend else conditions for other validations
}

def GetPopup(String popUpMessage)
{
String popUp = """<!DOCTYPE html>
<html>
