Hi!

I tried my best but can't quite get there.

UI Action Condition: gs.hasRole('itil') && !new ChangeRequestStateHandler(current).isOnHold() && new ChangeRequestStateHandler(current).isNext("closed") && ChangeTasks.activeTasks('false')

Script include name: ChangeTasks

Accessible from: All application scopes

Active: Yes

Script:

var ChangeTasks = Class.create();
ChangeTasks.prototype = {
   activeTasks: function() {

   var chg = new GlideRecord('change_request');
   var tsk = new GlideRecord('change_task');

   chg.get(current.sys_id);

   tsk.addAggregate('COUNT');
   tsk.addQuery('change_request',current.sysid);
   tsk.addActiveQuery();
   tsk.query();

   var count = 0;
   if (tsk.next()){
   count = tsk.getAggregate('COUNT');
   }

   if (state == 0 && type == 'emergency' && count > 0){
   return true;
   }
   else {
   return false;
   }
   },

   type: 'ChangeTasks'
};

let me just throw down a quick example.

I only only want this UI Action to be visible if the incident doesn't have any active incident childs

UI Action condition:   getChildInfo(current.sys_id);

Script include:

now this UI actions hides if the incident have any active childs and shows if it doesn't have any.

Yes UI Action is the best way to do this.
