Hi bbf3562,

I did with no success either and your other example seems to work if the array has already been created or established.  I think in my case the Array is being built in the while loop. 

while (sysCategory.next()) {
		var appProperty = {};
			var sysProperty = new GlideRecord('sys_properties');
			sysProperty.addQuery('sys_id',sysCategory.property);
		    sysProperty.orderBy('description'); 
			sysProperty.query();
			while (sysProperty.next()) {
				appProperty.groupName = sysProperty.getDisplayValue('description');
				appProperty.propertyValue = sysProperty.getDisplayValue('name');			
			}			
		data.appProperties.push(appProperty);
		}
