In Three20, can I not use custom table cells in a searchViewController?

I'm implementing a TTTableViewController with a searchViewController part, and I'm running into issues when displaying the results of the search in the search's TableView.

If I add TTTableTextItems to the datasource items property, it works fine, but if I try to add a TTTableCaptionItem or a TTTableImageItem or any custom cell I've created, the rendering is messed up.

Can anyone confirm that it's possible to use custom table cells in a searchViewController and perhaps point me in the right direction for how to make it work?

I've attached 3 screen shot to show what's working and what's not working.

No. 1: Works with this code:

[self.items addObject:[TTTableTextItem itemWithText:[item objectForKey:@"title"]]];

No 2. Breaks the layout with this code:

[self.items addObject:[TTTableCaptionItem itemWithText:[item objectForKey:@"title"]
                                               caption:[item objectForKey:@"excerpt"]]];

No. 3 Also breaks the layout with this code:

[self.items addObject:[TTTableImageItem itemWithText:[item objectForKey:@"title"]

OK, I figured it out. The key is setting the the variableHeightRows property to YES in the TTTableViewController that you're using as the search controller. Below is the code I've used.

TTTableViewController* searchController = [[[TTTableViewController alloc] init] autorelease];
searchController.dataSource = [[[MagazineSearchDataSource alloc] init] autorelease];   
searchController.variableHeightRows = YES;

self.searchViewController = searchController;
self.tableView.tableHeaderView = _searchController.searchBar;
