title: Reloading TTableView after DataSource items are added
body: <p>This is the code of my initializer:</p>
  
  <pre><code>if (self = [super init]) {
      self.title = @"Posts";
      self.variableHeightRows = YES;
      //XLog("");
  
      PostsDataSource *dataSource = [[[PostsDataSource alloc] init] autorelease];
      [dataSource.delegates addObject:self];
      [dataSource load:TTURLRequestCachePolicyMemory nextPage:NO];
  
      self.dataSource = dataSource;
  }
  return self;
  </code></pre>
  
  <p>In my datasource I'm doing a TTURLRequest and when <code>requestDidFinishLoad</code> gets called, my datasource gets filled with some items.</p>
  
  <p>This all works quite good, but my TTableViewController doesn't show any of these files because it gets initialised and displayed before my datasource is finished. I know it works, because caching my datasource to disk shows all items.</p>
  
  <p>The question is: How do I tell my TTableViewController to refresh the data out of my datasource file in my "requestDidFinishLoad" ?</p>
