UITableView crashes when the same row is selected twice

When i run the app and select a row it passes some information to EmployeeInfoPage and works fine. When i hit back and then select the same row. It crashes at the line tableController.empInfo = employee;. I get a EXC_BAD_ACCESS error

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{   
EmployeeInfoTableView *tableController = [[EmployeeInfoTableView alloc] init];

NSDictionary *employee = [[self.orderedSections valueForKey:[[[self.orderedSections allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)] objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row];

tableController.empInfo = employee;    

[self.navigationController pushViewController:tableController animated:YES];    

[tableController release];
}

This is the EmployeeInfoTableView.h file

@interface EmployeeInfoTableView : UITableViewController <UIActionSheetDelegate , MFMailComposeViewControllerDelegate, MFMessageComposeViewControllerDelegate>{

    NSDictionary *empInfo;
    NSString *currentPhoneNumber;
    NSString *currentEmail;

    UIActionSheet *callConfirm;
}

Then i use empInfo to set certain fields in the tableview.

This is my dealloc method

- (void)dealloc{
    [super dealloc];
    [empInfo dealloc];
    [currentEmail dealloc];
    [currentPhoneNumber dealloc];
    [callConfirm dealloc];
}

Is my error becuase i need to release any of my objects?

This is the error i got from off my iPhone, i really have no idea how to read this.

I don't see anything wrong with your didSelectRowAtIndexPath but your dealloc method is certainly not right. Never call dealloc in your code (i.e. only release the object when you're done with them).

Your dealloc method should look like this:

- (void)dealloc{
    [empInfo release];
    [currentEmail release];
    [currentPhoneNumber release];
    [callConfirm release];
    [super dealloc];
}
