NSIndexPath: message sent to deallocated instance - iphone

Question

Any help you can offer would be appreciated.
I have a app that has a tableView, detailView, flipView, and moreDetail View. It is fine moving through the transitions until the 26th element. The app crashes when I hit buttons that navigate to the flip and moreDetailView.
I am given the error Msg: [NSIndexPath row] message sent to deallocated instance.
I think I may be calling the indexPath too many times, but why does everything work well up until the 25th element and then stop working? How did the NSIndexPath get deallocated? I never deallocated it.
If you know, please help. Thank you!!!
Xcode says the problem is here:
#implementation produceView aka *detailView*
- (IBAction)showInfo {
FlippedProduceView *fView = [[FlippedProduceView alloc]initWithIndexPath:index];
fView.flipDelegate = self;
fView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:fView animated:YES];
[fView release];
}
- (IBAction) buttonPushed:(id)sender
{
picView *pictureView = [[picView alloc]initWithIndexPath:index];
pictureView.picDelegate = self;
pictureView.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:pictureView animated:YES];
[pictureView release];
}
-(id)initWithIndexPath:(NSIndexPath *)myIndexPath {
if (self == [super init]) {
path = myIndexPath;
}
return self;
}
#implementation picView aka *moreDetailView*
- (void)viewDidLoad {
RipeGuideAppDelegate *AppDelegate = (RipeGuideAppDelegate *)[[UIApplication sharedApplication] delegate];
self.picViewArray = AppDelegate.arrayProduceInfo;
NSMutableDictionary *dictionary = [picViewArray objectAtIndex:path.row];
}
#implementation FlippedProduceView aka *flipView*
- (id)initWithIndexPath:(NSIndexPath *)myIndexPath {
if (self == [super init]) {
indexes = myIndexPath;
}
return self;
}
- (void)viewDidLoad {
RipeGuideAppDelegate *AppDelegate = (RipeGuideAppDelegate *)[[UIApplication sharedApplication] delegate];
self.flipViewArray = AppDelegate.arrayProduceInfo;
NSMutableDictionary *dictionary = [flipViewArray objectAtIndex:indexes.row];
}

You should use properties (#property (retain) NSIndexPath *path;) instead of instance variables, so then when you do self.path = myIndexPath then it raises the retain count so it won't be deallocated when IndexPath is autoreleased.
