inheritance working on simulator but not on Iphone! - objective-c

Question

I have come across a weird error...
I have a class that extends another, getting some variables from it. Its a really simple one.
when i compile the code for the simulator, it works great. When I run in the Iphone, it get an error that states that the vairable is not set!. The code:
parent class header:
#import <UIKit/UIKit.h>
#import "TarefaMap.h"
#interface GenericTarefaTableView : UITableViewController {
TarefaMap* tarefaMap;
TarefaMap* tarefaMapOriginal;
}
#property (nonatomic, retain) TarefaMap* tarefaMap;
#property (nonatomic, retain) TarefaMap* tarefaMapOriginal;
#end
parent class implementation:
#import "GenericTarefaTableView.h"
#implementation GenericTarefaTableView
#synthesize tarefaMap,tarefaMapOriginal;
#end
child class header:
#interface EditTarefaViewController : GenericTarefaTableView <UITextFieldDelegate , UITextViewDelegate> {
Tarefa* tarefa;
NSArray *fieldLabels;
UITextField *textFieldBeginEdited;
BOOL isEdit;
IBOutlet UITableViewCell *cell0;
IBOutlet UITextView* textView;
NSManagedObjectContext* context;
}
#property (nonatomic, retain) NSManagedObjectContext* context;
#property (nonatomic, retain) IBOutlet UITextView* textView;
#property (nonatomic, retain) IBOutlet UITableViewCell *cell0;
#property (nonatomic, retain) Tarefa* tarefa;
#property (nonatomic, retain) UITextField* firstField;
#property (nonatomic, retain) NSArray *fieldLabels;
#property (nonatomic, retain) UITextField *textFieldBeingEdited;
#end
Child class implementation:
#import "EditTarefaViewController.h"
#implementation EditTarefaViewController
#synthesize tarefa, textFieldBeingEdited,firstField,fieldLabels,textView, cell0, context;
NSMutableArray *textFieldarray;
UIActionSheet *actionSheet;
UITableViewCell* cell1;
- (void)viewDidLoad
{
NSLog(#"ViewDidLoad");
[super viewDidLoad];
self.tarefaMap=[[TarefaMap alloc] initWithTarefa:tarefa];
self.tarefaMapOriginal=[[TarefaMap alloc] initWithTarefa:tarefa];
if ([tarefaMapOriginal isEqual:tarefaMap]) {
NSLog(#"SOMOS IGUAIS!!!!!");
}
NSLog(#"Comparando tarefas!!!!!");
if ([tarefaMapOriginal isEqualtoTarefaMap:tarefaMap]) {
NSLog(#"SOMOS IGUAIS2!!!!!");
}
}
This compiles fine on the simulator, but when i Try on the IPhone, I get an error saying that the variables tarefaMap is undeclared, and should be declared on the function...
any thoughts?

#interface EditTarefaViewController : GenericTarefaTableView <UITextFieldDelegate , UITextViewDelegate> {
before that line add this
#class GenericTarefaTableView;
then in .m file add
import "GenericTarefaTableView.h"
and change like in viewdidload
NSLog(#"ViewDidLoad");
[super viewDidLoad];
super.tarefaMap=[[TarefaMap alloc] initWithTarefa:tarefa];
super.tarefaMapOriginal=[[TarefaMap alloc] initWithTarefa:tarefa];
#implementation EditTarefaViewController
before that u have to import TarefaMap.h and also declare this in EditTarefaViewController.h file with like this
#class TarefaMap;
