I've been fighting this all day and can't seem to figure out what's going on.

I have a test method in which I need to have a Campaign Member, which is tied to a Contact. In the test method, I create an Account, Campaign, Contact, and Campaign Member.

The issue is that the Campaign Member seems to have no idea that the Contact's Account ID even exists. I can't see force Campaign Member to see it.

@isTest
global class TestGainsightUserGroupBatch implements Schedulable{
	
	static testMethod void GainsightUserGroupBatchTest() {

		// --------------- BEGIN SET UP --------------- //

		// Create new Account
		Account ACC = new Account(
			Name = 'Test Account'
			);
		insert ACC;

		// Create new Contact
		Contact CON = new Contact(
			FirstName = 'Test',
			LastName = 'Name',
			AccountId = ACC.Id
			);
		insert CON;

		// Create new Campaign
		Campaign CAM = new Campaign(
			Name = 'Test User Group Attendee',
			StartDate = Date.valueOf('2013-09-01')
			);
		insert CAM;

		// Create new Campaign Member
		CampaignMember CM = new CampaignMember(
			ContactId = CON.Id,
			CampaignId = CAM.Id,
			Status = 'Attended'
			);
		insert CM;

		System.Debug('---> Campaign Name = ' + CAM.Name);
		System.Debug('---> Campaign Member Account ID = ' + CM.Contact.AccountId);
		System.Debug('---> Campaign Member Account ID 2 = ' + CM.Contact.Account.Id);
		System.Debug('---> Account ID = ' + ACC.Id);
		System.Debug('---> Contacts Account ID = ' + CON.AccountId);

 I can always see the Account ID, and can see it when I just check CON.AccountID. It always returns null when I try to find it through the Campaign Member, though. Any ideas?
