Overriding Script Include: Question?

Hey Everyone, 

 

I learned that you can override ServiceNow's read only script includes by extending using the Object.extendsObjext. 

 

Below is the editable script include. I thought if I copied and pasted the function that I wanted to override in MIMWorkbenchUtilSNC, it would override, but it isn't. What am I missing?

The code from the read only script include.

Has anyone tried this? Please let me know.

In the out of the box script include, it is initialized by AbstractAjaxProcessor 

 

	initialize: function(request, responseXML, gc) {
		AbstractAjaxProcessor.prototype.initialize.call(this, request, responseXML, gc);
	},

 

After that it declares several variables within a function. 

addChildTasks: function() {
		var taskSysId = this.getParameter("sysparm_sys_id");
		var table = this.getParameter("sysparm_table");
		var selectedTasks = this.getParameter("sysparm_selected_tasks");
		var query = this.getParameter("sysparm_query");
		var parentColumn = this.getParameter("sysparm_parent_column");
		var type = this.getParameter("sysparm_type");

		if (!taskSysId) {
			gs.log("[addChildTasks] Invalid Parameter - sysparm_sys_id is empty or null");
			return;
		}
		if (!table) {
			gs.log("[addChildTasks] Invalid Parameter - sysparm_table is empty or null");
			return;
		}
		if (!parentColumn) {
			gs.log("[addChildTasks] Invalid Parameter - sysparm_parent_column is empty or null");
			return;
		}

 

So, why isn't the script include that I created doesn't override it? 

 

I literally just copied and pasted the below function to the new script include, but when I change the requiredFields variable values it doesn't change in the UI Page.  Not sure what else I need to do here. 

getTaskDetails: function(table, sys_id) {
		var requiredFields = ['number', 'sys_class_name', 'state', 'major_incident_state', 'sys_created_on', 'short_description', 'assigned_to', 'priority', 'category', 'description', 'close_code', 'close_notes', 'resolved_at', 'overview', 'lessons_learned', 'timeline', 'closed_at', 'active', 'problem_id', 'rfc', 'caused_by', 'cmdb_ci'];
		var gr = new GlideRecord(table);
		if(gr.get(sys_id)) {
			return {
				taskJs: this.toJS(gr, requiredFields),
				taskGr: gr
			};
		}
	},
