Hi there,

Wrote a custom controller to display an overall view of all our services, but the test method is returning a "System.NullPointerException: Attempt to de-reference a null object" on this line:

@IsTest(SeeAllData=true)
public static void testServiceTimeline() {				
		
	ServiceTimeline controller = new ServiceTimeline();		
		
}

This is my controller:

public class ServiceTimeline {
	
	public List<ServiceTime> serviceList { get; set; }
	
	public ServiceTimeline() {
		
		List<Service__c> ListOfServices= [
			SELECT 
				Name, 
				RecordType.Name,
				Address_Single_Line__c,
				Status__c,
				CreatedDate,
				Stage_Prospect__c, 
				Stage_Site_Survey__c, 
				Stage_Scheduling_Install__c, 
				Stage_Provisioning__c, 
				Stage_Pending_Billing__c, 
				Stage_Order_Received__c, 
				Stage_Order_Completion__c, 
				Stage_Obtaining_Install_Approval__c, 
				Stage_Awaiting_Install__c,
				Stage_Design_Request__c
			FROM 
				Service__c 
			WHERE 
				Status__c NOT IN ('Order Completion', 'Cancelled', 'Stalled', 'Unserviceable')
				AND RecordType.Name NOT IN ('Prospect','Ethernet Interconnect')
			];
		
		if (ListOfServices.size() > 0) {
			for (Service__c tempService : ListOfServices) {
				serviceList.add(new ServiceTime(tempService));
			}
		} else {
			Util.addERRORMessage('No Services are currently being installed.');
		}
		
	}
}

Any help would be appreciated.
