Tableview custom cell problem

Question

Hi everyone.
I created a iOS tabbed application using xcode 4.2 and storyboard. I added one tableviewcontroller with custom cell on it, when clicking the row, I want to open one tableviewcontroller, i used the following code below
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    categoryClass *cc = [datas objectAtIndex:indexPath.row];
    [tableView deselectRowAtIndexPath:indexPath animated:NO];
    iSubProducts *subProducts = [[iSubProducts alloc] init];
    subProducts.title = cc.categoryName;
    subProducts.catID = cc.categoryID;
    [[self navigationController] pushViewController:subProducts animated:YES];
    [subProducts release];
but when I click the row it gives me the following error:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath
on my iSubProducts tableviewcontroller, i have the following:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    static NSString *CellIdentifier = @"myCell2";
    iSubProductsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    productSubClass *cc = [datas2 objectAtIndex:indexPath.row];
    NSLog(@"Product Name: %@", cc.productName);
    cell.txtProductName.text  = cc.productName;
    cell.txtProductDesc.text = cc.productDesc;
    return cell;
I assume this is where the error occurs, the cell is returning a nil value. When I try to attach the iSubProducts tableviewcontroller using or from a button, it all works fine, but if its coming from row clicked, this error shows up.
Im quite new with iOS development, and maybe there is a error opening tableviewcontroller from a tableviewcontroller with a custom cell on it. I've been bangin my head for 2 days now and googled a lot, unfortunately I didn't find any solution. I'm pretty sure there's no error on the iSubProducts tableviewcontroller since its working if i tried pushing it from a button. Please I need advice on this one, Im so stucked right now with this issue. Thank you everyone.

Hi,
you need to create a tableViewCell in case the dequeueReusableCell-call doesn't return one.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    static NSString *CellIdentifier = @"myCell2";
    iSubProductsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
        cell = (iSubProductCell *)[[UITableViewCell alloc] init....
    productSubClass *cc = [datas2 objectAtIndex:indexPath.row];
    NSLog(@"Product Name: %@", cc.productName);
    cell.txtProductName.text  = cc.productName;
    cell.txtProductDesc.text = cc.productDesc;
    return cell;
