title: Data updating in a UITableView that's the rootview of a SplitViewController
body: <p>Hopefully I'll get some help here.</p>
  
  <p>Basic setup is this:  My application swaps out the current Main View of the Main Window each time I want to switch to a new view.  Why?  Because I wanted to use a SplitView further on in the program (what's displayed in the SplitView depends on what's been selected before it).</p>
  
  <p>What happens is the application reads in information from a text file, and populates a UITableView (1) with that information.  The user then selects a cell, and clicks "next".  The main window then ditches the previous table view, and creates a SplitView, which has a UITableView (2) as its root view, and another UITableView (3) as its detail view.</p>
  
  <p>So, I've gotten the reading-in-from-file part working, as well as updating the detail view (3) to show an initalized view based on what was chosen in the original UITableView (1).  However, I can't get the root view (2) to properly display options chosen from the original view (1).</p>
  
  <p>What I do is I have the Main Window pull out the string that contains a file-name base from the original view (1), and feed the line to the Root View(2)  of the SplitView.  This root view then reads in the data from file, parses it accordingly (All data structures are being intialized, and functioning properly, I've checked), and then sends the first item to the DetailView (3) to be displayed.  However, the root view itself remains blank, even though I updated the NSMutableArray it uses as a data source appropriately, and then called [controller.tableView reloadData].</p>
  
  <p>Everything is properly hooked up in the .xib file as well.  Does anyone have some tips that I can get?</p>
  
  <p>Sorry for the lack of code, but the code is on a secured computer, meaning no 'net access.  I can describe any code you want if you ask.</p>
