UITableView dequeueReusableCellWithIdentifier crash

Question

HI,

I've a strange problem concerning dequeueReusableCellWithIdentifier dequeueing a custom cell. It said that I am sending a message to a deallocated instance to an object inside that function, but I have not deallocated or released the custom cell since its creation. What could be the problem? Does deleting a cell in the tableview release the cell inside the cache as well?

Offending code:

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"TodaysOrderCell";
    static NSString *BlankIdentifier = @"BlankCell";

    UITableViewCell *cell;
    if ([outstandingOrdersArray count] == 0) {
        cell = [tableView dequeueReusableCellWithIdentifier:BlankIdentifier];
        if (cell == nil) {
            cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:BlankIdentifier] autorelease];
            cell.accessoryType = UITableViewCellAccessoryNone;
        }

        [cell.textLabel setText:@"No Orders"];

    } else {
        cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
            cell = [[[SingleOrderTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

            cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        }

        SingleOrder *order = [outstandingOrdersArray objectAtIndex:indexPath.row];
        [(SingleOrderTableCell *)cell setOrderData:order];
    }

    return cell;
}
