ViewController loses data after custom init - core-data

Question

So here's the deal: I have a custom UIViewController named FieldFormVC. In order to present it, I call this code:
FieldFormVC *fieldFormVC = [[FieldFormVC alloc] initWithFieldForm:(FieldForm *)[self getForm] andManagedObjectContext: managedObjectContext];
fieldFormVC.trackManager = self;
fieldFormVC.thisTrackNumber = currentScreenIndex;
fieldFormVC.textSize = textSize;
[navigationController pushViewController:fieldFormVC animated:YES];
Where [self getForm] returns a FieldForm object. The code for the initWithFieldForm: andManagedObjectContext: method is:
-(id)initWithFieldForm: (FieldForm *) f andManagedObjectContext: (NSManagedObjectContext *) moc
{
if (self = [super init])
{
fieldForm = f;
managedObjectContext = moc;
}
return self;
}
I set up some breakpoints, and when the initWithFieldForm: andManagedObjectContext: is called, the parameters "f" and "moc" contain actual values. At the end of the method, fieldFormVC has all the values it needs.
Now when it goes back to the first chunk of code and calls
fieldFormVC.trackManager = self;
All the values in fieldFormVC go to 0x00000000. All the properties of the fieldFormVC are set with #property (nonatomic, retain) and they are #synthesize'd as well.
The strange thing is that I have used similar initWith.. methods that have turned out great, and I've never seen this issue before. If it helps, I am using Core Data in my project, and FieldForm is a certain entity in my model. Thanks for any advice and help!
Update:
The getForm method's code:
-(NSObject *) getForm
{
WrapperForm *wrapperForm = (WrapperForm *)[[_fetchedResultsController fetchedObjects]objectAtIndex:currentScreenIndex.intValue];
FieldForm *fieldForm = wrapperForm.fieldForm;
PictureForm *pictureForm = wrapperForm.pictureForm;
if (fieldForm != nil)
{
NSLog(#"Class: %#", [wrapperForm.fieldForm.class description]);
return fieldForm;
}else if(pictureForm != nil)
{
NSLog(#"Class: %#", [wrapperForm.pictureForm.class description]);
return pictureForm;
}
return nil;
}

You are casting to FieldForm although your method getForm should actually return a FieldForm class anyway. Most likely the getForm method does not return the correct object.
